[cheering and applause] >> reporter: across the state in cleveland, protesters waited for trump's next appearance. >> i am out here today because the hate that donald trump is preaching across the country just needs to be challenged. >> reporter: a few demonstrators said the protests in chicago inspired them to come out. >> seeing my folks in chicago stand up the way they did, it just sparked something inside me it say, you know what, there is no better place that i can be at this moment right now than right here. >> yesterday in chicago we had a little bit of a problem. we came. we were not allowed to exercise our first amendment rights. [booing] >> reporter: also waiting for trump his supporters.

>> i watched the protest last night and i was a bit upset that trump was denied his right to speak. and that the people who wanted to see him were denied their right to listen. >> you have a right to protest but when it gets violent i shouldn't be protesting. >> reporter: these people have traveled from across ohio and beyond, many of them say they were planning to come here but feel it's even more important to attend after what happened in chicago. >> we want to show that we are not scared and that we are here to support him. >> reporter: inside, trump's fans had a chance to show that support when a handful of protesters interrupted. >> you know where they come from? bernie's crowd.

no one was pushing them, nothing like that. >> this is a private event paid for by mr. trump and he has the right to not have protesters here. >> reporter: and trump is now holding a rally in kansas city, missouri, there have been several disruptions by protesters but so far in violence. other presidential candidates have responded to the unrest in chicago last night. this is what two of the republicans had to say. >> dawned trump has created a toxic environment. and a toxic en has allowed his supporters and those who sometimes seek confrontation to come together in violence. there is no place for this. there is no place for a national leader to pray prey on the fears of people who live in our great country. >> we also have to look from the rhetoric come from the front runner in the presidential campaign this is a man that has told his supporters to beat up the people in the crowd and he'll pay their legal fees,

someone who has encouraged people in the audience to rough up anyone who stands up and says something he doesn't like. >> reporter: this is john kasich raps home turf. necessary a tight rice with donald trump. >> donald trump zip planning to hold another rally in ohio taupe. why is the state so important to him? >> reporter: well, if trump doesn't win ohio and florida in tuesday's primaries, randall, it will be a lot harder for him to secure the republican nomination in july. that's when the republican national convention will take place here in cleveland and governor kasich said if he doesn't win ohio he will drop out of the race. randall. >> and we are also hearing that rubio is urging his supporters in ohio to vote for kasich as a means of stopping trump. quite an odd political season we have here. thank you, roxana saberi. the two democratic candidates for president also condemned and blamed donald

trump for the violence at his campaign rallies. >> when he talks about, you know, things i wish we were in the old days, when you could punch somebody in the head. what do you think that says to his supporters? and what happened the other day when some young can man was being escort out and evidence sucker punched and we have seen other effect ar incidents. the issue now donald trump has to be loud and clear and tell his supporters that violence at rally is his not what america is about and to end it. >> if you play with matches you can start a fire you can't control. that is not leadership, it is political arson. [cheering and applause] >> the test of leadership and of citizenship is absolutely the opposite in our country. if you see bigotry, you should oppose it. if you see violence you should condemn it. and if you see a bully you should stand up to him.

>> senator marco rubio in "america tonight" in florida tonight railing his supporters ahead of that state's primary on tuesday. rubio has expressed confidence ahead of the vote that he will win his home state, but polls show that donald trump is leading among the state's republicans. trump has more than 40% of the vote, rubio in second place with almost 25%. senator ted cruz not far behind with 18% and governor john kasich in fourth place with about 9%. al jazeera's robert ray joins us live from pensacola florida where senator rubio is holding his rally. robert, are you expecting to hear more optimism from rubio? >> reporter: well, i think so. if you young it by the crowd here about 300 people, and an overflow crowd of people outside. you have ac/d.c. thunder struck blasting here right now. people are psyched to have him come out. marco rubio about to walk on the stage behind me at any moment

it's his fifth stop of the day and last stop in pensacola. and i think he will come out energized. randle, he has to this is his state if he loses severing on the line. >> latino's as you know are a major voting block in florida. how that vote split right now among the republican candidate? >> reporter: well, yeah, let's talk about the numbers a little bit. pardon my sheet here but there are a lot of them. there are about 1.4 million cubans here in the state of florida, 4 million hispanics. and those are very important votes for marco rubio and all the candidates frankly. right now, as far as the cuban population here, marco rubio has it. at 57% and we have seen some signs in this crowd throughout the evening there are cuban voters here. but donald trump has 13% of the cuban vote. and ted cruz 12%. so it looks -- it appears at least right now by the new poll that rubio will take the his are hispanic and cuban vote in

florida. but will that be enough? you know who, knows. 999 december99 delegates are whe taken here in florida on this second super tuesday coming up, randall and right now now, as you noted earlier, donald trump think has the lead here. >> now, we have heard or we read early their rubio was urging his supporters in ohio to vote to kassig, do you know if case sick doing rubio the same courtesy for kasich supporters to vote for rubio in this all-out effort to stop donald rump? >> reporter: yeah, we don't have any confirmation on that as of right now. but if you listen to what marco rubio has been saying he's disgusted by donald trump and what trump has been saying about him. trump is still calling rubio little marco. and it's just a real heck of a battle of words out here right now. and, you know, as far as senator

rubio making a descension as to whether or not he will even support trump, he said earlier today, that decision is becoming even harder if trump, indeed, gets the nomination in july. so the question is will rubio, kasich, cruz, any of them support donald trump if he gets that nod? >> thank you robert ray, we'll be checking back in with you. president obama is in texas stumping at democratic party fundraiser addressing several hundred donors this weekend in austin and dallas. mr. obama urge the both republican and democratic parties to engage in serious debate but also threw a if you jabs at republican hopeful donald trump. >> a debate inside the other party is fantasy. and schoolyard taunts. selling stuff like it's the home shopping network. [ laughter ] >> and then you've got the republican establishment, they

are very exercised. we are shocked that somebody would be saying these things. how can you be shocked? this is the guy, remember, who was sure that i was born in kenya. [ laughter ] >> who was wouldn't let it go. and all this same republican establishment, they weren't saying nothing. >> well, amidst the jokes which had jabs at trump wine, trump think steaks, president obama added he takes month pleasure in what is going on within the republican race. it is another election day in the presidential race today, republicans meeting at a hotel in heavily democratic washington, d.c. that caucus expected to go until 9:00 p.m. partial results are in from the wyoming republican talk with us 91% of the presinks reporting ted cruz is winning with 68%,

marco rubio in second place with 21%, donald trump inch a rare third place with 8%. there was also a republican contest in the far away territory of game. ted cruz picked up one delegate the other five there remaining uncommitted. for the democrats, hillary clinton won today's caucus in the u.s. territory of the northern marry an a islands and picks up four delegates with 50 officer% of the vote. bernie sanders gets two. now let's look at tuesday. both democrats and correct cans holding primaries in florida, illinois, missouri, north carolina, and ohio. northern mariana is up for grabs on the g.o.p. side. that makes 691 delegates on on the democratic side and 367 for the republicans. candidates are out in full forced to trying to sway voters before tuesday's big showdown on the republican side senator

marco rubio trying to make up ground in his home state of florida as we just heard from robert ray, john kasich and his wife karen campaigning in hay. current front runner donald trump began in ohio and then moved to missouri. which is where senator ted cruz and his wife heidi are stumping. joining them is former candidate carly fiorina who has thrown her support behind senator ted cruz. democratic front runner hillary clinton is in ohio also, joined by her husband former president bill clinton and vermont senator bernie sanders is addressing voters in illinois in an effort to further narrow the gap between him and mrs. clinton. tomorrow night in our sunday night look at the week ahead, presidential candidate donald trump and race as we head towards another big week of primaries, a look at the visible and sometimes violent rise of racism among some of his supporters. that's tomorrow night at 8:00 p.m. eastern.

violence continues to rage on as the war in syria enters its sixth year. today the warring sides said they will be in geneva when peace talks resume on monday. but the syrian regime says it will not discuss the future of president bashar al-assad. al jazeera's diplomatic editor james bays reports. >> reporter: both main sides now say they are coming to i can't neave a for the talks, the confirm also from the government come from the deputy prime minister and foreign minister at a news conference in damascus. but he made it clear the role of president assad was not up for discussion. >> translator: we are adamant on holding the integral integrity are you of syria at one state, this has been leased in the international documents included those released in an attempt to resolve the situation in syria.

>> reporter: those comments have angered the opposition, the u.n. have always made it clear that there should be no preconditions for these talks. the u.n. special envoy stefan de mistura in an interview for the talk to al jazeera program says that he hopes to get to the substantive issues on day way. >> in concrete, we can say that when we started talks in earnest, in other words, the substantive talks on the 14th, we will have some preparatory meetings before that. we will be able to at least tell everyone this is happening, therefore one is not enough and we need to push further. and, two, now we can concentrate on the real agenda. what is it? the political process. what is that? well, it is a new govern ants that's a very carefully chosen word in vienna to include something completely different

in terms of what we are having at the moment. second, a new contusion, not the old approach. and, three, new elections. with u.n. supervision. >> reporter: so the stage is set for an important day on monday. the first day of this round of talks and they are going to discuss the crunch issues, the future governance of syria. >> james bays. malala, president obama, nelson mandela, all of them recipients of the nobel peace prize and, now a city in turk is a hoping to join them. kilis, a city which borders syria is home to more syrian refugees than locals, al jazeera's laurence lee has details. >> reporter: on the hills overlooking the turkish border you can see refugee camps inside syria glinting in the sun. just few kilometer to his the north is the turkish town of kilis which serves as an example

of what can be done to help outside syria if the will is there. 90,000 to live here have been joined by 120,000 syrians. turkey has refuse today turn its back on. they, in turn, have set up businesses and worked together with their hosts. just outside the se the center e women were making firewood with their children, they have been here for four yards. not an easy life, but said this woman, they have been welcomed. she said she had no intention of attempting the journey across turkey and in to greece. that's likely to be because kilis has opened its front doors to the syrians. so kilis has been nominated for the nobel peace prize for all of them they believe their effort sews deserving they have even invited the european leader they admire the most, germany's angela merkel to come and visit of it's become standard for european commentator to to write turkey off it's for its lack of president freedoms, alleged

human rights violations and so off. but contrast in which the way turkey is managing the refugee crisis and the chaos of the european union couldn't be any great are. frankly it's quite hard to think of a single european town or city that could be nominated for the nobel peace prize. in the way that kilis has been. so what then do the authorities say to a europe of increasingly closed borders? >> translator: kilis today hosts more syrians than its own pop lake, citizens of kilis share their city, streets and even their air with syrian says, we believe the example of kilis should be recognize nighted by the e.u. and all countries in the united nations and this is why we think it should be awarded a nobel peace prize. >> reporter: of course elsewhere in turkey there is huge resentment towards the refugees but not in kilis. complaints in turkey has a very odd ring to them here. kilis, southern turkey. the u.s. has stemmed up effort to his defeat the rebel

group al-shabab. up next, a deeper look at the somali-based fighters responsible for the deaths of hundreds across east africa. and later the search for the next einstein lands in senegal, where top african scientists search for the continent's next great mind. >> the basic concept behind the whole thing is if people are laughing at them, then they are not taking them serious as a presidential candidate. >> and later the rhetoric of the presidential campaign inspires a whole new art form anti-trump art coming up.

the u.s. ramped up efforts in to the fight against al-shabab an armed group based in somalia. it generally receives little attention from the u.s. compared to isil and boko haram and al qaeda actual but al-shabab is regarded as a comparable threat. tonight, we take a deeper look at al-shabab. how it came to be. what its members want. and what recent actions by the american military mean for its future. washington says more than 15050ers died in last week's drone strike at a training camp in somalia. al-shabab was training members for an attack on u.s. and african union forces. preparation that his suggest al show job gaining strength and unafraid to garth never large numbers. the strikes comes almost a year after al-shabab's biggest attack on kenya's ga rizza university a cristal college. and before that it was behind the well-publicized hospital stilling situation at nairobi's west gate mall where 68 people

were killed in 2013. the group has also staged suicide bombings in and around mogadishu, but a al-shabab in is turns form is just the latest organization to battle for control in somalia. one of the world's most impoverished countries it has not had a stable government in more than 20 years, al jazeera's john terrett has more on the fight against al-shabab. >> reporter: this week u.s. involvement against al-shabab appears to be been stepped up. two incidents were made public. the u.s. said monday that american drones and fighter aircraft attacked an al-shabob training camp in somalia. 100 fist fighters were killed the pentagon says, there are no pictures not even cell phone video but the white house said fighters slated to depart the training facility posed an immediate threat to u.s. interests. >> the removal of those terrorist fighters degrades al-shabab's abilities to meet their objective somalia. including yes routing new

members and establishing bases. >> reporter: they spoke of the further movement against al-shabab. u.s. help comes flew somali forces on a mission, they didn't continues on the attack but two dozen fighters were killed report haded i but al-shabab says only one. >> i will state what we said previously there were u.s. forces in a trade, advice and accompany mode as they have been in the past in somalia. there were a small number of u.s. forces involved. >> reporter: al-shabab, the name means the youth is affiliated with al qaeda they are fighting to overthrow the u.s.-backed government in somalia which has very little influence beyond the capital mowing defe mogadishu oe tack tids is terrorizing the capital with massive car bombings like this which cause devastation in mogadishu. recently an al-shabob member set off a device on this so somali aircraft, despite the hole the plain landed safely. and news of this week's two operations against al-shabab

appears to speak to a desire by the united states and the african union to stop al-shabab at a time when isil is my greating from the middle east to africa in particular the muslim countries of the north and the east. john terrett, al jazeera, washington. >> joining me now in the studio is mike lyons a senior fellow at the truman national security project. and an al jazeera national security contributor. and in charlotte, north carolina, professor and their of the political science department at davidson college. professor, first question for you, who exactly is al-shabab? how long has the organization been around? >> al-shabab is a jihad i movement in somalia posed mainly of somalis but also nonso knowledge malis, we think it's been around since 2004, it was initially a small group who fought in afghanistan. by 2007, they had carved out a

very large amount of territory in southern so knowledge i can't remember but have been on their heels in recent years thanks for advances by the african union peacekeeping forces. >> what would you say is their primary objective? >> their primary objective is to stop the progress of the federal government of somalia to discredit it, to demoralize it, and to cause somalis to lose confidence in it. secondarily, their hope is to drive the african union peacekeeping forces out at which point shabob would be the strongest military organization on the playing field. >> let's turn to you now, mr. lyons, to what ex-texts is al-shabab a direct threat to the u.s. and their allies. >> they are virtual know threat to the united states. however they do threaten the region and ally that his we have in the region and it's a good example of a microcosm of what's happening in these middle

eastern countries they threaten the government if we don't take care it have now it will continue to grow and ma as it at that size and become a greater problem but for today it's not a threat to the united states. >> for most of us we first heard about it this with blackhawk down are any of them involved descendants of that conflict? >> maybe later in the life. al-shabab literally translated means the youth. it's become the alternative for what is a challenging country inside somalia without any employment and the youth that it offers to those that are young in the country. but really, no. it's a relatively new movement that, again, it catches firing because of what's happening inside the world as the world becomes smaller and also is a learning organization that sees what's happening in other terrorist organizations it's more affiliated with al qaeda than isis right now. it's changed its tactics lately and been very successful.

>> so back to you, professor, to what extent would you say the african union peace enforcement mission has been o or has not bn effective in suppressing or taking on al-shabab? >> it's been partially effective. it has protected the federal government of somalia reasonably well. it's protected key installations in the capital. it has, because of its superior fire power it's been able to push shabob out of all major cities of southern somalia including mogadishu, forcing al-shabab to operate mainly from remote rural areas and rely more on a network of operatives in the capital and other cities to operate hit and run suicide bombings and other terrorist attacks. the problem for the african union peacekeeping forces is they can't finish this job. shabob now is very difficult to target. it's diffuse, it is engaging in these a sim he had rickal

terrorist attacks on its terms when and where it wants it's a job for the somali army to finish it and it's not been capable of do doing that. >> how many people do you think comprise fighters for al-shabab? how many folks are we talking about? >> they have estimated about 7,000. it's a small relative force, a micro come of what exists in other locations. so from an offensive military briefs speculative you need a force of 20 to 21,000, three times to go on the offense to totally wipe them out but as at professor said they went on a decembeasymmetrical warfare it s more than just the drone strikes of the united states. >> we have seen one fist fighters killed last weekend by the american drone strike. professor. some of the people in al-shabab are denying that it happened.

saying some of the leaders we said were killed were not killed. what do you make about this? how significant was our strike? >> whether or not it happened i think it's pretty clear it happened. the details none of us knows right now. i think what is most important about that air strike is the precedent that it set. up to this point the u.s. government at least in the obama administration has been pretty reluctant to use force in somalia. it has, but only for very surgical strikes on top leaders of al-shabab, do date they have not gone after rank and file new recruits in training camps like this, so this is a big change. apparently. in tack takes on the part of the united states, it seems to signal that they -- the government sees a need to support the african union peacekeeping forces in the air and frankly, given the fact that shabob is operating in rural areas trying to hit african union forward bases, they are

quite vulnerable. we can see them from satellites and so this is a tactic that could certainly set shabob back. there is dan danger, though, ofw back as we know from other places when you kill large numbers of people most of whom are probably just kids with no ideological commit to him al-shabab, just there for the salary, you make all of their klansmen, their extended families very unhappy. so time will tell if this will have positive or negative impact. >> do you have any idea, mike, who is providing al-shabab with the funds to pay the fighters for the material, the weapons, and how well are they armed? do they have tanks, for example? >> well, no, what they have done is they have stolen it from amazon and the somali government. they have changed their tactics, they have recognized that they have to get material somehow, they can't create it themselves so they have actually stolen it similar to what isis did inside of syria and iraq. and then they train odd it quickly and easily and they are age to turn it back against, you

know, these are countries that have come inside of somalia and you know, they are not necessarily fighting for their own country. so from a soldier's perspective. >> the african union troops. >> they don't have the same -- possess the battle as much as it would be a somali government or somali sit is sen because they are coming from outside. they are attacked the forward bases anbases and taken the equt and turned it around them. that's a stray i didn't that won't hold off railroad long. >> the african union troops are there because somalia did not have its own fighting source to what extent is progress being made on on so knowledge yadi gen arm that i can count they are. >> it's slow. the first thing they do is protect the current government, leader and capital. you go outside that area similar to afghanistan you get outside that have region and it's the wild west, there is no control. the capital doesn't control

cared which allows terrorist organization to his run free. >> professors, final question for you, to what extent is al-shabab in touch with, in sync with isis or al qaeda? at one point they pledged loyalty to isis. which is at odds with al qaeda as i understand it? >> al-shabab as pledges lil' to to al qaeda central. there was a small wing with dissidents within al-shabab that pledged support to isis. they have been marginalizeized d a few killed by al-shabab that's an internal feud that reoccupied them for a enough of months. at present the most important thing to note about that question it doesn't make a lot of difference they can don't rely heavily on al qaeda it never has, no not month money, material support, recruits. so for the moment, this is a largely academic question. that could changeover time.

>> well, there is one more question, mr. lyons, do you think we'll see more involvement by u.s. military against al-shabab in somalia evening as the u.s. focuses on so many other conflicts in that ring none. >> i think this administration will continue the course that it's doing, it's going to provide the over the horizon type of drone operations that they get -- if they get a target of opportunity they'll take it. you won't so any u.s. troops on the ground. somalia is also a place where we have lost american soldier soldo there is a sensitivity part of it on the pentagon as well. i don't think you'll see any changes to this administration, they don't see it as a threat. they want the somali government to take care of the problem. >> thank you very much for joining us on al jazeera. and also to our guest professor in north carolina. thank you for being with us this evening. >> thank you. up next the search for africa's next einstein. some of the world apt top

scientists garth never west africa. they are there to meet some of the brightest young mind on the continent.

>> our american story is written everyday. it's not always pretty, but it's real... and we show you like no-one else can. this is our american story. this is america tonight. troops from south korea and the u.s. are in the milled of large-scale military exercises. it's an annual drill to test their defenses against north korea. this year's exercise comes a midst heightened tensions on the korean peninsula. rob mcbride has details. >> reporter: this is a show of force intended to impress.

one of the set piece drills of these annual exercises involving thousands of troops from south korea and the united states. and they come at a time of increased tensions on the korean peninsula. in response to these drills, north korea threatened preemptive strikes. while its leader kim jong-u.n was shown on state media inspecting missile tests. far from provoking north korea says the u.s. military, this show of force insures stability. >> at the end of the day we inning cyril believe in peace through strength. and it is in the strength of our alliance that we believe that we can deter an avoid war. >> reporter: north tree acclaims these exercises are a prelude to war allowing south korea and its ally the united states to buildup forces ahead of an invasion, that's always denied but the u.s. contingent this year is the largest ever, doing

little to ease the fears of the north. out at sea a short ride offshore by military aircraft, some of the vessels assembled for these war games. like this assault ship. carrying up to 3,000 sailors and marines when deployed for conflict. but the commander of this force insists these exercises have been planned for well off a year. >> this is not in response to anything that north korea is doing, but we dong it's important to show the commitment to the alliance and our readiness. >> reporter: getting ready for whatever, or whenever the next crisis will be. rob mcbride, al jazeera, south korea. hundreds of african scientists gathered in senegal this week in hopes of finding the next einstein, the african institute of mathematical sciences works to closes the development gap between africa and the rest of the worlds,

nicholas hawk has more from senegal. >> reporter: he sees the world in numbers. he believes everything from the universe to the decisions fishermen take out in the ocean have an equation. he is the son of a senegalese peanut farmer and an einstein fellow. one of the brightest math ma tipses on the african continent. >> what inspired me about einstein was his ability to [ inaudible ] everything. to try to have another way of looking at everything. try not to say okay, there is a universal truth in a sense. >> reporter: the african institute of mathematical sciences is where he works. top academics including nobel lawyer yells teach african students who can't afford to go to m.i.t. or harvard but are just at bright. like this man who group a remote village in zambia with barely enough to eat and no electricity at home.

he spent his childhood hungry staring at the sky. he now studies coz knowledging. >> believe you me we are going to invents a lot of things and here. more of [ inaudible ] and it will come from here. [ inaudible ] >> reporter: the african academics behind the school have started the next einstein forum. a fellowship for the bright young mind whose work are too often neglected but need toy to be highlighted. organizers seek to address the problem. the work is offense undervalued and over looks because it comes from the continent. they are sharing their innovations with top policy maker, business leaders and

academics. >> it's something of world of aids has totally overlooked. you know, $1 trillion has been spent over the last few decades in aid to africa. almost none of it on generating expertise in africa to design and implement its own solutions. and we have seen the consequence. solutions from outside don't work. >> reporter: for being an einstein fellow is an opportunity of being part of something bigger. he hopes his mathematical skills may some day unlike some of the deepest mysteries of this world. and its untapped resources. nicholas hawk, al jazeera, senegal. just when you thought you had heard everything about donald trump, now something new. art inspired by trump's red rick. >> if people are laughing at him, then they are not taking him serious as a presidential candidate s. >> art is sending a message next.

especially in the authorities. the myth of nuclear energy, of it being economic, safe and clean has been swept away. >> "fukushima: a nuclear story," narrated by willem dafoe.

seattle is looking to break new ground for workers' rights again. two years ago the city passed legislation that raised the minimum wage for $15 an hour. now members of the city council want to give workers consistent schedules. sabrina register reports. >> reporter: when a hollande a greenberg isn't out walking her dog you can find her at starbucks where she works as a

barista. >> i love the customer interaction, that's definitely what keeps me going every day. >> reporter: it's a job she's held off and on for the past decade. while she says she enjoys helping people find that perfect drink, her work schedule has often been unpredictable. >> i would fluctuate one week i had eight hours, another week i had 38. which was a little crazy. >> reporter: it's a complaint seattle city councilmember lorena gonzales says she hears a lot from the city's lowest wage earners, including hospital in retail, home healthcare, and the food industry. >> people who are at the bottom, people who have the least amount of wealth and opportunity are women and people of color who work in hourly minimum wage jobs. and so we have, i believe, a moral obligation to correct that. >> reporter: gonzales is one of a couple of seattle city council members now working on what she calls secure scheduling

legislation. the proposal would likely require employers to provide workers with two weeks advanced notice of their schedules, it would also require employers who want to hire more staff to offer part-time workers the option of goal full-time. and it would prevent what's known in the restaurant industry of where a restaurant worker establishes a restaurant one night and reopens the next morning. >> it's a problem that happens everywhere. we would regularly have in problem sunday in to monday. >> reporter: university of washington professor who has been studying the affects of seattle's 15-dollar an hour minimum wage ordinance says prohibiting these type of worker schedule practices could cost employers. >> businesses that are asking people do this whether it's working consecutive shifts or having a lot uncertainty, they more or less know it's not great for the worker but it's good for the business. and so if the city council were to pass an ordinance a hro*pbs

long these lines it's shifting the balance in favor of the workers but increasing the cost of doing business. >> reporter: the proposal already has the attention of the state's restaurant industry. which responded by saying as employers in the hospitality industry, we are concerned about what a mandated restrictive scheduling pog is a could mean for our employs and our businesses. cities like san francisco are considering similar legislation, something uncommon just a few years ago when federal and state laws addressed labor concerns. >> it's been within the past few years you have seen a certain cn set of cities move in this direction they are doing it because that's where the will exists. >> reporter: councilmember gonzales says secure schedules along with the 15-dollar minimum wage, gives people the best shot. >> it's all of these things coming tote that will create an environment where working poor families will really have a shot atta chiefing the american

dream. >> reporter: a dream that may come with higher costs for businesses in seattle. sabrina register, al jazeera, seattle. have you heard about the new app people. it's controvertial. the critics warn that people could become a platform for online bullying or cyber revenge. al jazeera's jake ward has more from san francisco. >> reporter: the con set sent is straightforward users of the people app can rate other users in three categories being personal, professional, and romantic. now being the makers of the app which went live on march 7th, write that its purpose is to provide a reference check for the people around us. >> so if there was an app that was like the yelp for people what, do you think about that? >> reporter: the internet has the power to literally ruin lives. when this concept was announced there was an explosion of negative feed bam. right, really review people, he's a jerk being she's really

cool. didn't seem to fit. since then, the company has changed the app's speecher so it avoid being an arena of anonymous criticism. here is people's co creator julia codry explaining the changes on the dr. phil show. >> you are not anonymous on our app. you cannot have your profile started by anybody else. you have 100 percent opt-in ability. and we really want to make sure that you have full control over what goes live on our app. >> reporter: so what's wrong with that? reviews are one of the great inventions of internet age, whether you are one wondering we to eat dinner, you want to hire someone and you read that i have referenctheirreferences. as long as people don't hide behind a pseudonym, what's the big deal? it's one thing to write a review about a product or place or even someone's professional qualifications it's another thing to write a review of their quality as a human being.

there is a whole world of dating apps out there and their makers don't include reviews at all. the reason is pretty simple. here is how one app builder described it to us. >> the chemistry and the faith is something that you cannot review it's very subjective. it's very personal. somebody who is great for you may not be not so great for somebody else. and so i think just the concept of reviewing people is just not appropriate. >> reporter: here is where people have really crossed the line. although the company says you can't publish a negative review of someone who isn't on the app and the app is all about positivity. the company has told several outlets that it's considering a so-called truth license in, which paying users could access unpublished negative reviews of even nonusers of the app. and the terms and conditions give the app irrelevant revocable ownership of anything written on the platform. this is not just a place for casually jogging down a review of something you made or did. it sums up who you are and it

behind the whole thing is if people were latching at him, they be they are not taking him serious as a presidential candidate. >> reporter: the collection has grown. over two dozens in all. images depicting trump as richie rich. at former chairman mao and even hitler. just the stuff that comes out of his mouth is just -- it's scaring me and it feels like this is, you know, this is how it started with hitler. >> reporter: the crown jewel of thomas' collection is actually a porcelain thrown. >> the inspiration behind this was i think that he lies about everything that he's saying and hessentially he's full of [ beep ] and that's the title of this piece, full of beets. >> reporter: hof [ beep ] >> don't trump is calling foy a total and complete shutdown of muslims entering the united states. >> people were upset and shocked but people weren't that angry. it was kind of confusing for me. they were like, no, no, it's

just funny. he's so crazy. no one is taking him seriously. and i am like, actually, he just said like the most vicious hate speech that he could making us feel as though we might be the japanese back in the '50s here in the u.s. or the jews were treat ed in nazi germany. >> reporter: muslim actor and comedian created a mock you. are you about a fiction the character dropped trump illegitimate daughter. if trump supporters are white, evangelical muslim haters, then the one thing donald trump cannot say he loves is muslims. he can't say, oh, it's so great that a muslim woman is playing my muslim daughter. i love it. oh, it's great, it's true. he can't say that. >> reporter: they both understand that their work will likely draw more attention to the man they fear could be president. but both say it would be worse
