thanks for watching. i'll see you next saturday at 5:00 p.m. eastern. until then like us on facebook.com/politics nation and like us on twitter at "politics nation." now my colleague philip mena. this hour the fire storm intensifies over the president's controversial tweets. a new report says his top aids fee he didn't understand the seriousness of the remarks and exactly one week later he is still attacking the squad. plus senator bernie sanders speaks exclusively about the 2020 race and his opponents ahead of the second democratic debate. and a big week ahead in waugsz as robert mueller testifies in public. what to watch for and what his testimony could mean for the president. but first breaking news this

hour. puerto rican governor announcing he will not seek reelectioning 2020 and said he would no longer head up the new progressive party. the embattled governor is facing massive pressure after it leaked private messages where they allegedly made homophobic, misogynistic, and sexist remarks of victims of hurricane maria. and today marks it it it -- and. the president renews his twitter war after an art in the "washington post" gives a peek into the tweetsz and the subsequent rally in north carolina. said his own top aids didn't think he'd fully understood what he had done last sunday when

heified off a series of racist tweets and aids and advisors him to tone it down but he reacted by further ratcheting up the attack. phoney sources that don't exist is fake news. es for the only thick people were talking about is the record-setting crowd and tremendous enthusiasm. i don't think they're capable of loving our country. they should apologizes to america and israel for the hateful things they have said. the rhetoric got people talking on the sunday monning shows. >> the reality is this is a guy worse than a racist. he's actually using racist troeps and racist language for political gains. trying to use this as a weapon to divide our nation against itself. >> but as usual the republican cavalry rushed to thes president's defense.

>> they say i'm scared and i've never in my total of 37 yes in public services ever heard a constituent say they were scared of their leader. >> do you believe president trump is a racist? >> i believe he is -- yes. no doubt about it. >> let's bring in our guests now. we have former republican congressman david jolly and strategist drew litman and staff writer that hill scott wong. "sadly ironic that a naturally born citizen that became president is preaching love it or leave it to a fellow citizen who is naturalized. only apawn taking an oath to protect against all enemies foreign and domestic." can you expand on that? >> sure. look, representative omar took

an oath promising to defend the country. one thch greatest expressionses off love someone can have is to renounce the citizenship of their birth place friendship for omar that was somalia. to say he doesn't believe they're capable of loving the country, he takes the level of despikability to all it new heights. which is why the silence of republicans is damming. they left their country. that's why they left and they are expressing a love that our founders envisioned and wanted to protokt. the ability to challenge their president. donald trump doesn't have the intellectual maturity to understand the framework which he's throwing insults or he doesn't care and frankly i think it's the latter. >> he's emailinging a socialism

approval poll today. asking their views on the subject. >> that's silly stuff. it's going only to supportsers. a few are going to write back and say i'm all for socialism and that's what i want president trump to pusue as part of his reelection. it's a talking point briefly. >> scott, the president said if the soenter back chants happen again he might tell them to stop. something it tells me this might happen again. what do you think the president will do that next time? >> if i'm clear, i mean the president is unpredictable. i don't think his initial go back tweets earlier this week were part of any grand campaign strategy. i don't think he looped in a lot of people he was going to tweet that. his campaign now is saying that there are benefits to the president putting that message out there, unifying democrats

around the four progressive law maker, whom have said contravlgs remacks in the past. i think he's trying to link all the democrats with the four progressives. the tweets come at an interesting time because they were at time when nancy pelosi was pushing back and distancinging hesedistancing herself and other moderates. and now the president has unified democrats around these four progressive women. >> themize deissed to walk back those comments after pressure from the gop. how do you think republicans feel today after his renewed attacks? >> donald trump -- he got the blowback, so he tried to pretend

i didn't have anything to do with this. this was a crowd in north carolina. and when the media reports he's apologizing or softening, donald trump typically leans back in. so i think we will hear this chant from now through 2020. if we don't hear this chant, it will be love itto leave it which is just as dangerous. that suggestest as quieting of descent, that you must agree with your political leaders or leave. this strategy -- and i agree with scott that it's just boris populism. es for this may help him in the presidential race but will insure a wipe out of republicans in the house of representatives. es for he's insuring democrats will keep the house. the suburban districts reject this type of narrative. he's hurting house republican's

chances of taking back the house, even if he thinks he's shoring up an electoral strategy for himself. >> congressman omar was welcomed back home with great fan fair. do you think this should give republicans pause. that these are going to further unite democrats? >> it's going to help congresswoman omar and help her get reelected. and the republican's positions on other issues have been so vehement and unreasonable, that you see support rising to the democratic position on climate change, abortion, guns which democrats can campaign on. some of that seems to be driven by the desire oppose trump in the belief that whatever position he has is wrong. >> and a bit earlier we were trying to get to the republican defense of president trump. i want to listen to what white house advisor steven miller had

to say on fox. >> i think the term racist has become a label too often deployed by the left, democrats in this country simply to try to silence and punish and suppress people they dis gree withx speech that they don't want to hear. >> what do you think? >> i think trump's defenders are twisting themselves into a pretzel to explain a way trump's tweets. es for i want to return to something that david jolly said earlier about the difference between what house republicans want to see. this is clearly detrimental to their ability to take back the house of representatives in 2020. we saw that specifically with kevin mccarthy and other members of the leadership team having an intervention earlier this week saying you have to talk to the president and distance himself, have him distance himself from the "send her back" chants at

his rally. republicans know that will hurt them in an incredible way come 2020 in the house of representatives and do them harm in trying toing take back the house. >> you were a former member of the republican patty in congress. i wantb to know how different it is now from the one you knew when you were in office? >> i used to believe there would be voices to counter this nativism, if you will. what we have seen -- a lot of people say the president's given permission to the elements we saw in north carolina. and we can look back at history where mccain took the microphone and said barack obama is a decent man and we have fill sauf canical differences. the it greatest heart break to me is how republicans embraced

donald trump as it did with donald trump himself. we ask why do republicans on capitol hill keep defending him? it's time we judge republicans on capitol hill for defending him. tra that's why i left. i don't see a republican capitol hill whose leadership i trust. donald trump will come and go. they are getting his back and we get to judge them in the same lens and light as the president today. >> that day is going to come shortly. thank you all for joining me. now to the latest on the 2020 presidential race. bernie sanders is campaigning in iowa and we earned all he would be on the debate stage with elizabeth warren july it -- >> reporter: senator sanders just finished a two-day swing

focusesing on his plan for medicare for all. what we've seen the past week for the first of the nation caucus goers is a fundamental debate about medicare for all verses the balm care plan. and biden saying it was such an effort to get it in the first place, now is not the time to transition to a medicare for all system and might not be achievable in the first place. senator sanders really responding, forcefully pushing back on that. let's take a listen to the conversation. >> people talk about what's realistic. in 1965 we're not anywhere nearer the technology we have today. the united states government was able to establish a medicare program guaranteeing health care to old people. so i cannot understand when

people tell me over a four-year period we cannot expand medicare to every man, woman and child in this country. it is doable. it is what we have to do. >> reporter: you're going to share ardebate stage with senator warren. what do you hope to accomplish? >> senator warren will talk for herself. but i think the theme for me will be to talk about the war against the working class of this country for the last 45 eryoos and the incredible level of wealth and income and equality we have. >> reporter: talking about that first head-to-head match up with senator elizabeth warren. we also asked earlier this weekend about what he thinks democrats voters will see and he says in one word with, intelligence. a serious confrontation between the british navy and iran. we'll hey that tape next. we'll hey that tape next

the british government and royal navy knew this was going to happen because they gave them ample warning days in advance. this comes days after, weeks after the british government detained an iranian oil shipment called the grace one off the coast of gibraltar. of course gibraltar belongs to britain. and that would be in violation of international sanctions barring the sale of oil to syria and this was seen as a retaliation they haven't been able to come up with a solid reason for why they detained the ship. and it was found today that boat was not actually anywhere near iran. it was more in omony territorial waters. so right now this really isn't

looking like any kind off legal issue, mare time issue. it's looking like tit for tat between two major powers. iran and the united kingdom and in the background is the rising tensions between the iran and u.s. said the u.s. shot down an iranian drone and all of this happened because president trump backed out of the deal inked under inobama administration. and they're getook be trying to look for some kind of diplomatic way to defuse this situation. as it's going, it's looking like a bit of an eye for an eye and that doesn't necessarily lead anywhere good. >> we all end up blind when that happens. this is just anath other stn the renewed hostilities.

they jamd and destroyed an iranian drone thursday. and the trump administration is considering ending a program that allows iran to run a civilian program that's a key pat of the 2015 iran nucledeal that the u.s. has pulled out of. this sl happening while the u.s. has no permanent leader at the pentagon. counterterrorism is on the agenda when pakistan's prime minister meets with president trump on monday. es for -- former spokes person for the un. we know tensions are high with iran as we've discussed. is this the highest you've seen? >> no, certainly not even in my own time in the government. in 2012 when a lot of the public

discourse was about iran going to war a lot of people were worried about it and sanctions were at their peek. to me this is not that new. what's new is this tit for tat behavior. that's pretty new. shooting dou shooting down drones is not new. but when you're talking about 30% of the world's sea born oil goes through, that's concerning. the thing that's the most consonning i see for example is this isn't actually tit for tat. for the iranians to believe that is false. the foundation is wrong and the reason is the british were enforcing sanctions law. that's why they detained the ship off the coast of gibraltar. for what the iranians are doing in detaininging and seizing ships in the is plain

provocative behavior. i don't expect this to lead to fullouter wa. >> you're covering tensions. and the u.s. is trying to expand the pentagon's presence there. can you tell us more? >> absolutely. we're seeing for the first time i think that there it's not just about the u.s. and iran. the u.k. is involved, russia is involved and china is involved. and unlike the internation with north korea, iran does business with these countries and theetds countries want to do business with iran. and u.k. is obviously -- they're doing these actions. they seized a ship in gibraltar. saying they're enforcing a law but i don't think anyone didn't expect that would be seen as a provocation from the iranian side and as we saw iran seized a ship. right now i think the u.s. is sort of caught between this

whole -- i don't know how i would say it becauses the trump administration has an internal contradiction in their policy where trump himself says he wants to step back from what's going on in the world and we saw that recently when he was speaking by the white house is said this was not an american ship. this was a u.k. ship and talked about energy independence from the persian gulf. there's talks of a coalition being formed to protect interests in the region. i don't know how much president trump wants to commit to enforcing in the region and wanting other people to step up. >> you don't think he thought the dominos would start to fall after the u.s. pulled out? >> there's this notion to face

an adversary a country wants to be united. in the u.s. and iran you have hardliners, people more willing to talk and engage in diplomacy and in trump's own out look there are contradictions. these forces they obscure the it plot when it can comes to what are you try doing? what is the trump administration trying to do? maximum pressure is not a strategy. it's a position. >> the maximum pressure goal here -- trump said this when he abdicated from the goal last may. the first thing he mentioned was about undermining iranian's nefarious region and the behavior has gotten worse since the deal and it's gotten worse since the deal. right or wrong, by the way. i don't think he should have

abdicated from the deal but hiss goal was focussed on that. so in his mind is to increase his leverage as much as possible in order for ultimate negotiations. something interesting i'm sure you noticesed is the song that the administration has been singing has changed a little bit in that pompeo said they need come to the negauche yaotiating. and we know iranians said they wouldn't do it without restrictions being removed first. and we did this is onces there its an agreement to pursue negauche yag negotiations there are certain restrictions that can be placed on hold. it's funny because although president is trying to undue a lot of what president obama did, i see him pursuing the same path

with increasing leverage as much as possible. there is a possibility for negotiations. we'll see. >> in its current form, do you think this deal can hold on and for how much longer? >> no, i don't and the reason for that is the iranians, when it comes to europe, they want economic sanctions and europe just can't deliver on that. the trading system they set up is focussed on humanitarian trade and it's not really functioning that much. at the owned of the day european financial institutions are afraid to gelt in the crosshairses of u.s. sanctions. dpra so they're not going to see the reparations they need from europer to uphold their deal and they've already begun enriching uranian past the level set by the deal. that doesn't mean their are

close to a nuclear weapon. i'm not concerned with the steps they've taken but that being said, it's hard to see the deal hold up and ultimately both sides will be forced to the table. >> i want to speak to you about one of our allies, pakistan. do you think that will help improve relations between two countries? >> honestly i think anytime it comes to diplomacy, it's important. we've seen a lot of posturing and when it comes to pakistan as well. dprrs ploemacy takes courage. it takes courage to open channels and say we need have a conversation about what's going on. things are getting bad in the region and pakistan is right there. iran has relations to pakistan, these countries and wasn't that long ago there might be an issue with india, cross border strikes.

so when i said before trump has this noninterventionist tendency, that works but needs to by replaced with a strong foreign policy that includes demonstrations. even though we don't have an agreement, there's no missiles flying and hopefully ewe'll get there soon. >> next we have breaking news. puerto rico's governor says he will not seek reelection after eight straight days of protest. eight straight days of protest (vo) parents have a way of imagining the worst...

breaking news this hour puerto rico's governor announcing that he will not seek reelection in 2020. he made the announcement in spanishish live from his home and said that he will also step down as the head of puerto rico's new progressive party. the address after tens of thousands off protesters took the streets for over a week calling for the governor's resignation. this stems from group chats win

the governor and his innercircle made sexist and homophobic comments including joke about dead bodies accumulating after hurricane maria. joining me, thank you both for joining me. governor now says he's not resigning now. he's just not going to seek reelection. es for >> i mean he went fugtrther and said i welcome the process the puerto rican legislature set out to see if there's possibility for impeachment. i don't think this has any indication it would appease the critics. tomorrow possibly the biggest march we've seen in the hiszry of puerto rico and that's bigger than wednesday where they said

hundreds of thousands showed up to prots and demand him to step down. tomorrow organizers and people that are like trying to round people up to us and everything happening on the island until he steps down. in the busiest highway of puerto rico. so we'll see what happens. >> and cars being stopped because of all the protesters. what's your initial reaction? >> i was certainly surprised. the protestsers have been very clear and the message is that he resign. the message wasn't for him to step down of his party orrer for him to seek reelection. i think tomorrow's march/protest, it's going toing be something we want our eyes on. because the protests wednesday broke records.

this one can certainly become historical. >> you don't think it will calm some of the protesters because he said i'm not going to dwoo this again. let me play this out. >> our reports say the crowds have grown exponentially day by day. es for so by tomorrow the crowd is going to be biggest. we've seen how artists have been brunging pop thool march. right now one of the biggest latin pop stars put a pause in his career to attend the protest. >> another artist in the island people love said i am halting my vacation and returning to thenne island to be part of this. if you have to wait for ricky martin to show up in the island, it says something.

like alejandra said, protestserses have been very clear and consistent. they have been protesting for ail eight days in a row. sources are telling local reporters that in his head he thinks people are going to get tired eventually. school is going to start in august and peopleera aren't goi to organize or protest as much. we'll see what happens now. i listen but i'm not thinking about following your demands. >> how can he governor going forward if you have this many people showing up, what does he do? >> that's the big question and so many people from his administration have resigned, been fired. so you have the secretary of education right now she was arrested and she's going through an investigation process right

now for alleged embezzling of more than $15 million. and same with avala, she deals as lot with medicare and medicaid funds, stuff like that. that person is in the same spot as the education secretary. so that is a big question. the governor epicooses insisting he can govern and he says he's committed to restoring the trust that the people put in him but i mean nobody -- not a lot of people seem to follow with that. so that is a big question right now. >> the person next in line not there anymore because of these scandals. what do you think it's going to look like going forward? >> when you look at the facts, protestsers don't want him in power.

his own political party does not want him in power. he has lost the trust of puerto ricans the people in his cabinet. so can he govern this way? i don't think so. >> we're going to find out. to pea continued tomorrow. governor will not seek reelection. not resigning. holding steadfast there. coming up trump verses the truth. was the president telling the truth when he said he tried to stop the "send me back" chants earlier this week. me back" chas earlier this week. eh, not enough fiber... chocolate would be good... snacking should be sweet and simple. the delicious taste of glucerna gives you the sweetness you crave while helping you manage your blood sugar. glucerna. everyday progress but allstate helps you. with drivewise.

president trump reignited his twitter war with four congresswoman of color. the president tweeted this morning i don't believe the four congresswoman are capable of loving our country. they should apologize to america. he went on to add they are destroying the democrat party but are weak and insecure people that can never destroy our great nation. president trump took heat over how he handled chants in north carolina on wednesday where a crowd of his supporters chantd "send her back" talking about congresswoman of minnesota, omar. the president tried to distance himself and deny that he paused while it was happening too.

so in case you forgot, let's watch that. >> president, if i may, when your supporters were chanting "sentd her back" why didn't you ask them to stop saying that? >> number one, i think i did. i disagree with it, by the way but it was quite a chant and i felt a little bit badly about it but i will say this i did and i start started speaking very quickly and it started rather fast as you know. >> as result of the house in a 240-187 vote condem the president's remarks. next. this is the couple who wanted to get away

it's been 125 days since releasing his report. here's what the chairman of the house committee says this morning. >> this is a presidents who is violated the law six ways from sunday. if anyone elsz had been accused of what the report finds the husband presidents had done, they would have been indicted. >> it's a pretty damming set of facts showing a campaign welcoming help from a hostile foreign pow. >> shows evidence that the president is guilty of high crimes and misdemeans. >> joining me executive produce of the podcast, "talking fesds." former u.s. attorney and deputy assistant attorney. thank you for joining me today. will mueller's testimony be the end of these investigations or is this going to open new doors for congress to take action?

k >> i would expect it's the beginning off more investigation. the question is whether they can do it in a way that's effective to tell the arc off the story. the story begins with the russian davila. and then move to the obstruction, which is them covering up what they're willing to do. it's kind of an artificial situation because they will look at obstruction before the attack and that's odd. so they have to find a way to ask the questions to tell the story to the american people about what happened. if they do that effectively, then that will open doors to pursue other parts of the investigation. >> harry, "the new york times" af article out this morning talks about the 88 articles before congress and insight what may happen this week. it says over decades of

appearances before congress, mr. mueller showed a little patience for politics and grew weary with the partisanship that came with legislation oversight. will mueller be a reluctant witness you think or will he end up being the democrats' hero in all of this? >> neither. he's reluctant. he doesn't want to be there. this is like one long root canal with him. remember he agreed to show up rather than litigating, what everyone in the administration is doing. i have seen some of those 88 appearances. he tries to be responsive. he's a really polite and generally thoughtful person. so he won't shut them down and be antagonistic. he will try to stay within the four corners but history shows he may give them a little. and what little that is outside the four corners will be critical, but they've got to start with the facts. they've got to start with sort of bite-size pieces that just are leading questions, just have

him say, yes, yes, i've found this, i found this, as to the key episodes nadler was talking about at the top of this segment. >> cynthia, i'm curious, if you were on one of these committees, what questions would you ask robert mueller? >> if we're talking about the obstruction section, i think what's important to do is ask those leading questions like harry was mentioning. you know, and focus on the acts of obstruction where he found there was substantial evidence. substantial evidence in the mueller report is prosecutor speak for yes, he would have been indicted for this. that means did the president try to fire mcghan and mueller found there was substantial evidence. so my question would be, first, did you find that? and then let's explain that. can you tell us what were the facts that supported that and why you found them compelling? and i would go through that with particularly each of those things where he found the substantial evidence to support the obstruction.

harry, same question. you can ask robert mueller three questions. what is it going to be? >> so totally agree. first -- with cynthia, first you have to salt away the most important. it would be nice if he says it in his own words. but if not, you walk him through the report. that really is 9% of their task. after that i think there are two things they can try. first is focus on the letter that he sent to the attorney general, taking issue with the attorney general's characterization. he's not going to criticize bar but you can establish some daylight. the home run question if he would answer it, and i think unlikely, it would be but for the doj policy that says you can't indict a sitting president, would you have recommended -- would you have found the president committed criminal conduct? you want to ask that in such a way so if he rebuffs it, you don't get a bad soundbite and it doesn't come back to sort of bite you on tv.

president provided trump wrote he did not recall, remember or have an independent election on more than 30 occasions. >> it's clear they did not find everything they wanted to find. that there were questions that were unanswered. >> cynthia, how much can these untruthful witnesses hinder the investigation? >> well, according to mueller, they were a big hindrance. it will be interesting when he sits down they talk about it and he discusses exactly what the problems are. where are you going to go from here? they're done. manafort, who lied to him repeatedly, and blew up his plea deal, is sitting in jail until he dies and he's not -- he's not going to ever tell them exactly what happened. so that's the problem. even though for instance trump constantly said he didn't rule, he's never going come to them now and tell them what actually happened. it's been impaired and i'm not
