hi, everyone, i'm john siegenthaler. this is al jazeera america. crunch time, voters hear the final pitches. at stake much more than the balance of power. and right to vote, your guide to voter id laws, and other possible complications at the polls. pass port control, america steps up screening. the rising fear over isil fighters coming to the u.s. new clues on the deadly rocket plane crash in the

desert. and climate change, why the u.n. says the window of opportunity is closing. ♪ after the most expensive midterm campaign ever, election day is almost here. the candidates are down to the final push. the big prize tomorrow, control of the senate. if republicans take over, it will be even more difficult for president obama to get his agenda through congress. that includes getting senate approval for the president's judicial nominee. tonight we begin with david shuster. >> john, we're told the number of early ballots now number 18 million. republicans are trying to get a pickup in north carolina and turn it from blue to red, democrats are trying to flip georgia and turn it to democratic blue.

in georgia the percentage of early-ballots cast by african american voters now stands at 33.1%. that is a larger share than the 2012 presidential election, and 13 points higher than the african american portion in 2010 midterms. this would appear to be good news for the democratic candidate. she and her party have been counting on a strong get out the vote campaign. it appears to be a similar story in north carolina. take a look at the number of registered democrats as a whole in that state, versus registered republicans. there have been 1.1 million ballots. and 20% of the early voters are independents. this could be a boost for democratic incumbent, senator kay hagan, polls have shown her

slightly ahead of her republican opponent. we'll of course have the final word tomorrow night. john? >> david shuster thank you. and by this time tomorrow we should have some early election results. senate democrats in the south are locked in a tight reelection campaign. african american votes could make the difference in many states. randall pinkston is in new orleans tonight with more on that. randall. >> reporter: john, the incouple banth democratic senator will need more than african american voters to win reelection, but if those african american voters don't turn out in big numbers, she stands to lose. in her campaign since 1996, mary has counted on a unique recipe of louisiana voters for victory. pollster silas lee has a phrase

for it. >> we have unusual political gumbo. the conservative north, and the somewhat moderate to conservative south. you also have this gumbo of protestants and cat -- catholics. >> reporter: african american voters traditionally don't show up for midterm elections. >> now it's a question of mobilizing them and getting them to the polls, and that means you have to dedicate resources. i'm not sure how much resources they are dedicated. >> reporter: here few signs of excitement about the election can be spotted. only placards urging people to vote. >> what has changed is not always what is seen, but what is happening behind the scenes, in terms of idding voters, voter

mobilization, that may not be as visible. >> reporter: what is visible, a $27 million banquet of political commercials. they have cooked up almost 70,000 tv ads. her principle opponent says the right recipe is to put president obama at the top of his menu. he appeals to voters by linking landru to the president. >> 18 years in senate have changed the center, and she now represents washington, d.c. i suspect you have seen that clip, the mayor of dc. there is a lot of truth to that. >> mary sold out louisiana and the country, quite frankly with the louisiana purchase with obamacare. she is done as far as i'm concerned. >> abbas the country, president obama is the wedge issue for

many republicans. here in louisiana, there is a stark racial divide. a university of new orleans poll suggests fewer than 20% of white voters here approve of president obama's performance, compared to 80% of black voters. >> the south has not always been the friendliest place for african-americans. it has been a difficult time for the president to present himself in a positive light. >> reporter: landru says the extra ingredient is her 18 years in the senate. >> don't people remember what she did with respect to bringing in money for katrina? >> they forgot. they have a very short memory. >> reporter: that's why she is counting on voters like this. >> i want somebody who will

event my interests. crime, education, housing, just promoting self-sufficiency among the citizens of new orleans. >> reporter: with eight senate candidates none are expected to get more than 50% on election day, so a runoff in december is the likely result here. you have heard david shuster talk about early voting in georgia, there have been pretty dramatic numbers here too compared to 2010 when there was about 133,000 early voters. this time there was a 181% increase. but there is split opinion on what that means in terms of whether there will be a big turnout, and a huge african american turnout. >> yeah. people might just be voting early instead of more voting. randall thank you. tomorrow voters will face new voting times, dates, and new

laws. jonathan betz is here with that. >> yeah, there are changes in this election for some voters after a year of state slashing, early voting, eliminating same-day registration, and now also requiring id's. one of the big campaign issues is not who to vote for, but how. a year after the supreme court gutted the voting rights act, some voters will face new voting times and rules. seven states now require voters show a voter id on election day tomorrow. three more don't require a photo, but want some sort of indication. know toe id has become a part of our every day life. >> reporter: laws in other states will go in to effect after this election. >> if you are trying to vote illegally, then it may be possible that you are getting away with it, and nobody is ever

going to know. >> reporter: but critics call it voter suppression, a way to keep certain groups from the polls. those who show up without id's face varying rules. in some states voters sign an affidavit promising they are who they say are. and others use a professional ballot. some states require the voter return to an election office within a few days and show an id. and others like north dakota simply say no id, no vote. activists worry the new laws only discourage further turnout. >> and voter's rights group say they will be there if anybody has problems. and the fbi will have investigators throughout the country to investigation allegations that come up. >> since 2000 we have seen this

sort of stuff and problems with many elections, so we'll see tomorrow. thanks, jonathan. voter turnout expected to be low throughout the country. turnout in the u.s. is consist engineerly the lowest in the industrialized world. >> reporter: they crossed seas, picketed presidents, and crossed borders all for the right to exercise their rights. john lewis appreciates that prize. he says the vote is precious almost sacred, and calls it the most powerful non-violent tool we have in a democratic society. so how come so few of us actually vote? the pew resent. center found that in the midterms only 37% of voters voted.

only one in four americans are registered to vote. non-voters are poorer and less educated than active voters. more than half don't have a credit card, and fewer than half went to college. and the reasons given for not voting are as varied as the makeup of those who stay away. in a survey in 2012 many weren't interested, even more didn't like the options, but the largest group said they simply didn't have time to vote. the non-profit is not surprised. they explain that tuesday was originally picked as voting day so as to allow for three straight days of worship, one market day, and two days of market day. but that was made in 1845 when texas wasn't a state. while many americans just can't be bothered to vote, others

couldn't care less about that. this was the founder of the conservative movement. >> i don't want even to vote. elections are not won by a majority of people. as matter of fact, our leverage in the election quite candidly goes up as the voting populous goes gown >> reporter: orer tos like that continue to reduce ballot initiatives of today. as we earn, we vote, as we have children, we vote, as we age, we vote, and though it seems small, if we can drive ourselves to the polls, we are four times as likely to vote. so if your polling place is less than bustling on tuesday, that quiet is just your fellow citizens, the ones that voted to stay home. michael shurer, al jazeera. these are the top issues

voters care about according to goog google. and jake ward is here with more on that. is this part of the google trends that i look out to find out what the top stories are? >> it is number this is really just a look at the search terms. google as you know has almost endless incite into what we are searching for. i spoke with daniel seaberg and asked him which races are seeing the most activity? >> the top search candidates include rick scott from florida, bruce ronner from illinois, scott walker, and mary burke from wisconsin, and then chary christ who is also in florida. we see there are a couple of ways to look at them. number one people looking at their professional history and voting record, so how they voted

on abortion, what their stance is on legalizing same-sex marriage or marijuana. if it is a relatively new candidate, we see a trend towards looking up their personal history, their family, and in both cases whether it's somebody who has been in office or not, we often see people looking up their net worth, and in some cases this is very high, in other cases it is rather modest, so it's hard to see if there is a correlation around choosing that person if they are worth more or not, and how old they are. the age of cap dates is something we see pretty universally. >> so jake, do they predict what is going to happen? i mean the people at google probably know who is going to win? >> right. google has in the past been able to predict the outbreak of, say, a flu, using search activity. and i asked them if they could

make those same sorts of forecasts for political races. >> we're not in the business of predicting elections yet. it's difficult to understand somebody's motivation behind a search query. they were able to look at searches that tie directly to people who have the flu. people who are exhibiting symptoms and looking for treatment, versus people who hear about the flu or hear about a flu outbreak, and they are able to look at that data and separate them out. when it comes to people's political motivations, their beliefs, the choices they make, the decisions, motivations, why they search for something, there are a lot of different variables at play here, so what we do, is we look at what people are searching, we look at the trends, we look at it geographically and look at it over time, and we can go back and see different comparisons,

look at different issues, and we provide that information to analysts, to the media, and we let those folks make sense of it, and think about where it plays into the greater context of the election itself. >> john, i think it's worth noting that google wasn't in the business of predictions yet. so i think in the future they will be -- >> it's not just searching, let's say for rick scott, but all of the other information surrounding that. google knows more about me and anyone else than any other organization in the world. >> that's right. his point is it's easy to know whether someone has the flu or they don't based on how they search. but it's hard to tell whether someone is leaning towards mary

la la landru or not. >> that's fascinating. if you share frustrations, take a picture using the hashtag hear congress i want. and tell us what you want. we have already heard from many of you about your frustrations. "america tonight" coming up next will share some of your responses. many young voters could be among those opting to stay home. only 25% of young voters are expected to show up to the polls. >> truth is where you find it. >> reporter: 24 years ago, rock the vote got madonna to rock to young people on mtv. ♪ rock your vote, rock your vote ♪ >> reporter: today the group is spreading the same message with

different celebrities on youtube. >> what we have seen is this video go farther and wider than any video in a midterm election. >> reporter: the internet is now the main source of news for millennials, and almost all of them use cell phones that means the way groups like rock the vote is changing with a focus on twitter, facebook and websites like rockthevote.com. >> since we developed the online registration tool, we have processed 6 million registrations. >> reporter: only one in four plans to go to the polls this year. that's about the same propersian as in the last election. the league of women voters get millennials to sign cards and

then they will get reminders like this. >> we'll say remember you said you would voted, here is a reminder, here is your signature. >> reporter: young people can register on the website which offers details about candidates and issues. it predicts at least 85% will go to the polls. this graduate student is one of them. the league sent him this text on halloween: >> they go to your environment, and bring up the issue of voting and the importance of it. >> the main reasons young people give for not voting are a lot like those of the general population. many lack confidence in government and are suspicious of politicians. our complete coverage of the midterms begins tomorrow night,

7:00 pm eastern time. we'll have results and what those results could mean for america. coming up next, though, in this broadcast, how a kid from canada became a radicalized fighter in syria. plus a warning that says it will be soon too late to fix an immediate

unprecedented effort to slash emissions. but they say even if all fossil fuel emissions stops right now,

the impact will last for centuries. >> we have a very limited window of opportunity, and the global community must look at these numbers and show the result by which we can bring about change. >> reporter: the u.n. calls this the most comprehensive study on climate change to date. may joins us now. she is the executive director of 350.org. welcome. >> thanks, john. >> this report says climate change will inflict quote severe, widespread, irreversible impact unless the world's carbon emissions are cut rapidly. you almost get the feeling like they are saying it is too late. is it too late? >> it's not too late actually. this is definitely the strongest warning we have ever gotten, but what this means is the science is clear, the economic case is

clear, and now there's historic levels of public support, so it's the politician's turn to act. >> and fossil fuels must be phased out by year 2100. is that possible? >> it is possible. if you look at germany, one of our strongest industrialized countries, they have been able to transition their economy to renewable energy in record time. so we can absolutely get there. >> the worst offender is what? china? the united states? >> well, there's lots of ways to answer that question. we have a lot of work to do here in the united states. we're the highest per capita emitter in the world. coal is one of the bright spots. look at what we have done here in the united states. we have been able to pressure the proposal for hundreds of new coal plants in this country, so

that movement has been quite successful. >> move to natural gas? i mean that's what has happened in a lot of states. >> you are right. >> in coal country, in kentucky, they changed from a coal-fired plant to a natural gas plant. is that better? >> you are exactly right to ask. and gas is not better. new studies are showing the life cycle emissions of natural gas are just as bad. >> not cleaner? >> not cleaner? but right here in new york city, 400,000 people marched on the streets about climate change, and i was here. and there's this great public movement all around the world, so with this report and that movement, we can push to see change. >> i love your optimism, but i think about the polls that show jobs being the number one issue that americans care about. and some people say that's in

direct conflict with environmental issues. what do you say? >> i say there are no jobs on a dead planet? >> but it might not be dead for a hundred years, and clearly we're not thinking in the future. >> well, here is one thing about the ipcc report that was made abundantly clear. the business plan of the fossil fuel industry, and the needs of the human species on this planet are incompatible. so we have got to turn this around, and a transition to renewable energy will create lots and lots of jobs when we need them most. >> there are still some ads running this election night that say that we don't know. >> well, i will say this, the movement is active in red states and blue states. if politicians are smart they will pay attention to what the voters are saying.

>> thank you for coming to talk to us. stade the st. louis county of police said his department did not try to keep media helicopters out of ferguson, flight restrictions were put in place when violent protests broke out, following the police shooting and death of michael brown. a new report says the restrictions were an attempt to keep news helicopters away. the police chief said people were shooting at helicopters and the restrictions were about safety. >> the faa started this conversation with the police department because of the number of shots reported. we had air crews reported seeing muzzle flashes from the ground. >> coming up next, the new security steps to keep isil fighters out of america.

and the new world trade center about to be open for

it is election eve. in many ways this is one of the most important midterm elections. there could be a power shift in the senate, and that would come as the u.s. faces major crises around the globe. one of the most challenging isil. more than 300 members of a sunni tribe have been systematically slaughtered in recent days. today the united nations security council condemned the

latest massacre. tribe leaders blamed the government for not giving them weapons and supplies as it tried to fight isil alone. isil has pushed away in some places despite intense u.s.-lead air strikes. now there's growing concern over the u.s. strategy. nick schifrin sat down with the president of the syrian revolution. >> john, good evening, many people i speak to along the syrian border have a lot of criticism of the u.s. policy in syria, criticism of u.s. air strikes, saying the targets are not enough, and there is not enough coordination ] and criticism of the plan to train moderate fighters to fight isil. they say that program isn't fast enough. and they say that the program and the strategy from the u.s. simply isn't solving the humanitarian crisis, and the

worst refugee crisis since world war ii. is president obama's strategy for syria working? >> i think if we work with good faith and good partnership, we will take sure it will work. but i hope our american friends can listen more to us. >> reporter: so far has that strategy worked? >> right now, there's no foot strategy. there is only air strikes. >> reporter: has there been any coordination between the u.s. air force, the u.s. military, air strikes on the ground in syria, and the free syrian army commanders who are on the front line? >> there is no coordination at all between the free syrian army and the command and control center, which is doing the air strikes currently. but we are insisting that this should be developed as soon as possible. >> reporter: you have asked for

training and weapons. president obama has promised $500 million worth of training and weapons. have you trained any more training or weapons in the last two months. >> the way it is being handled right now, the program will be to late. we don't provide assistance and help to these forces, then we are running the risk of losing these forces, which are very good fighters on the ground against isil and the regime. we are not asking for any boots on the ground, all that we are asking for were just the aid and supply of weapons and munitions and we will do the fighting. >> reporter: since we spoke there has been a major setback to u.s. policy in syria. some of the u.s.'s most important allies, those moderate syrian fighters who get training and weapons, one of the major groups has lost its base to

al-qaeda. it's called the revolutionary front, and we need them in order to fight against isil. and there's new video of their base being overrun by al-qaeda, the al-nusra front inside of syria, and those are u.s. weapons that al-qaeda group, the al-nusra fighters have taken over from the revolutionary front. and what subpoe-- is happening syria, and they are battling on three fronts, against the regime, isil, and the al-qaeda fighters. and they say there isn't enough help for them to defend themselves against al-qaeda and the syria regime. there is not enough coordination with the air strikes, for them to make any advances. so they ask this question, if we're going to overrun, fighting against al-qaeda, and fighting

against the syrian regime at the same time, how can you expect us to defeat and degrade isil when isil fighters are using the american weapons that they stole from the iraqi fighters. >> tom is in washington, d.c. tonight. welcome. how would a republican-controlled senate challenge the white house on foreign policy issues like let's say iran and nuclear negotiation? >> great to be with you. thank you for having me on. i think they would try to exert pressure in both the populous area by making much more aggressive statements from the pulpit that they would be afforded. for example, senator mccain on the armed services committee, and trying to prevent the president from leaving sanctions on iran in the event of a nuclear deal, but at the same time the president is the commander in chief and will

maintain a lot of power after the elections whatever happens over foreign policy. so i think it will be at least to -- a basic degree pretty limited. if we remember -- >> let me stop you there. let's continue with iran. if -- if the president cuts a deal with iran and then congress fails to -- to give its approval, then what does that do to the foreign policy negotiations and the relationship -- the new relationship, if there is one, with iran? >> well, i think a lot of republicans will be very skeptical if there is a nuclear deal that allows iran to retain quite a lot of its nuclear infrastructure, which is what we seem to be moving towards. that being said, there have been statements coming out of the white house, unnamed sources talking about the president's ability as they see it in the

white house to release sanctions -- or to remove sanctions by executive order, even if the senate doesn't approve releasing those sanctions. so there will be a big debate about the president's executive power as it relates to iran. certainly with republicans in control of the senate that will be a very big broaching point. but the president is the commander in chief. president bush still maintained a lot of control in iraq, even though democrats took control of congress. >> let's talk and syria in iraq now. if senator mccain becomes the chairman of the armed services committee, would we see a different strategy? he has called for ground troops to go in. and it doesn't seem the american people are in support of that.

how can he play a role when the president is in charge. >> general dempsey -- you have seen statements about the need he sees and quite frankly as i see it for some social forces on the ground embedded with the iraqi units. but the president is the one that ultimately makes that decision, and he is the one who controls what the united states military does, and i think it's probably unlikely that simply because the republicans take control of congress, if they do, he will fundamentally change his opinion and outlook. i think more than anything it will be down to the judgment that he sees with his in addition -- national security people rather than with congress. >> does the fact that the senate controls the purse strings on the pentagon budget, will that

give republicans a greater say? >> i -- i think it's unlikely, because i think republicans -- the only way they could do that, would be to cut off funding for the military, and i think that would be something that they would not want to consider, based on how that would be perceived of not supporting the military, and how that might look towards 2016. i think certainly if you see republicans putting more pressure on the president with iran, it will be interesting to see what hillary clinton does there, in her view, because she is going to be thinking about 2016, so as much as one election will be open, the next election will be immediately at the forefront of the public discourse. >> and the response from prime minister netenyahu if republicans take over the senate? >> well, relations between the obama administration and prime minister netenyahu's coalition in israel are clearly toxic. i think that's actually even a

mild word to describe it. there have been movements by the party of which netenyahu is the prime minister to reach out to republicans below the surface to try to pressure republicans to take a tougher line. but quite frankly, again, it comes down to that basic point that the president ultimately for right or wrong, good or bad, however people see him -- belief he is the one who makes those decisions. >> some of the candidates including some republican candidates are suggesting that if voters elect them, they will be able to effect those issues. so we will see. tom thank you very much. the u.s. is adding new security checks for millions of foreign travelers. homeland security says it's an effort to stop isil fighters from entering the u.s. >> good evening, john, it's another sign of rising concern

about terrorist threats from overseas. the administration announcing they are going to be tightening procedures to screen citizens of allied countries who fall under the visa waiver program. citizens of those countries do not require a visa to come to this country. they do have to go online and fill out a form before they come here, and it's there they will be subject to increased scrutiny and tighter security measures. jay johnson saying in part: part of the issue here john is duel citizenships. they could travel to iraq and syria to fight, for example, on the side of isil, and the

united states and the other governing entities wouldn't even know they were there because they have more than one pass port. an estimated 1,000 individuals a month are traveling to the region to fight for isil. other forms of scrutiny include asking individuals, trying to determine whether they have ever traveled under an alias. so another indication of rising concern about foreign fighters in syria and iraq. >> mike viqueira reporting. mike, thank you. there is concern about recruitment in north america to fight overseas. in canada one young man become radicallized without her parents knowing about it. >> reporter: growing up in calgary, dame -- damion was

bright. but as a teenager, things started to change. >> i think he was just trying to find where he fit. and it was difficult. he struggled. once he hit about 15. he started keeping more and more to himself. >> reporter: at 16 damion dropped out of school. he became reclusive and depressed. counseling didn't help. >> the day after his 17th birthday, he attempted to take his own life. oh, boy. didn't see it coming. he seemed like he was getting better. >> reporter: soon after she says her son converted to islam. she was relieved. >> after all of the turmoil we had been through, the emotional states, the depression. when we convicted to islam, he found this peace within him. and he would sit with the family

and just -- i could see that i could relax. >> reporter: for three years damion seemed happy, working, at peace. but then he moved to a new apartment, and that brought him to this downtown mosque. >> he must have met new people, because that's when things started to change. >> reporter: and how did they change? >> there was more agitation within him. he started talking about 9/11 conspiracy theories. he started talking about other countries and the wars that they had there. and there is damion raiding the pantry and the frig again. >> reporter: this is the last video she has of her son. drifting around the edges of a family halloween party. the next month he traveled to the middle east. he told his mother he was studying linguistics in egypt. instead the troubled 22 year old

went to fight alongside extremists in syria, joining al-qaeda linked al-nusra. >> i don't buy into, i went to the internet, liked what he said, i'm going to be radicalized. i don't buy that. there is somebody actively talking to them. >> reporter: in the arab social media there is a lot of focus on the internet and radical groups devote resources to slick propaganda and recruitment videos. >> they can be introduced to the ideology -- >> reporter: but this veteran of policing, trained in counter terrorism, believes the internet alone doesn't create would-be terrorists. >> you need somebody pulling the strings, guiding him down that highway of indoctrination, so all of this normalizes in his head, and we says yeah, this makes sense to me. >> reporter: have you found

those people here in your city? >> no. no. we know they are there. we have been told they are there. >> reporter: the chief says the promess of becoming radicalized ending up as a foreign fighter in a place like syria is in many ways no different than the path to a gang for dealing drugs. they are working now to develop an intervention program to identify at-risk teenager who are at risk of going off of the rails. and it's not just canada, a chicago teen who was arrested at o'hara airport in early october with his younger brother and sister. he had bought and paid for the tickets, arranged pass ports, and they were on their way to go join isil in syria. he was in court today charged with attempting to provide a terrorist organization with

material support, and that is a very serious charge, john. >> this is so hard to understand, and after watching your piece, if we could go back to the mom for a second. does she have a better understand now than she did earlier about why this happened? >> she spent a lot of time since her son's death talking to other mothers in the united states, in canada, and in western europe, and what she has realized is that there is a script; that as chief hanson said, it's not just about what he was watching on the internet, it was about someone speaking directly to him. they know the alias of the person. they don't know his real name. but he has said, i gave them the books. i argued him out of his doubts, and he is the person who took him to turkey, and delivered him to alus in are, and is believed

to have done the same to many other young men and women in north america. >> so based on what you are telling us tonight, this hasn't stopped, so is there anything the u.s. and canada can do to prevent this from happening? obviously they haven't been able to do it yet? >> calgary has an experience with a really ferocious gang war. and in trying to deal with that, they started a very aggressive program of early intervention, that goes into the schools and really works with at-risk kids. the part that was missing in calgary, and missing everywhere, is what happens to kids after they leave school. and they are developing a program where friends, family can go to the police and look for support, working with a social worker and other professionals who might be able to reach that young man and

redistrict their path. and that is really what is key. the intervention part we're told over and over again is the key piece f out. >> really fascinating. and you can see more of sheila's report coming up at the top of the hour. a new beginning in lower manhattan. plus the debate over plans to rebuild part of the roman coliseum. why the works

out. they first said republican supporters are more likely to transfer in bad weather. and decided voters tend to turn out twice as much as undecided

voters. and voters that make less than $50,000 tend not to turn out if it is bad weather. we are going to have some of the key states that are in bad weather tomorrow. we're talking about kentucky as well as arkansas. some of the other states will have marginal weather, alaska is going to be a very rainy day for them. what is going to be happening here across the midwest, we have a front that is starting to develop, that is the one for arkansas as well as kentucky that we're going to be watching because we're going to be seeing a lot of rain and thunderstorms all the way down. even in texas, though it's not a key state, we'll see major rain. beautiful weather across the east as well as most o plane.

>> reporter: investigators say there was no explosion before the virgin galactic spaceship crashed. >> they found the fuel tanks, the oxidizer tanks, and the engine, and all were intact and showed no signs of burn through. >> reporter: the safety board which is leading the investigation, says a reentry system was prematurely deployed shortly after the craft broke up. it helps the craft land by decreasing dragged, but was unlocked early. cockpit video shows the pilot unlocking the fathering system prematurely. but this was a statement of

fact, and not a cause, and that months and months of inquiry will follow. virgin ga -- galactic's owner said he would not be deterred. >> it has had a horrible setback, but i don't think anybody would want us to abandon it at this stage. a new beginning tonight for the famous skyline of new york city, one world trade center is open for business in lower manhattan. this is a live picture of the building all lit up tonight. it standing right next to the spot where the twin towers stood 13 years ago. its first tenant is already

moving in. >> you can't let it affect your life. you have to live your life and carry on, you know? >> reporter: with reinforced concrete and sleek modern style, it is also the most expensive building ever built in the western hemisphere. coming up, new security concerns in france after mysterious drones were spotted flying over at least a dozen nuclear power stations. plus we'll talk with another daredevil about their high-sky feets. that and much more coming up at 11:00 eastern, 8:00 pacific time. italy's culture minister supports a plan that would let visitors stand where glad aidtors once fought. >> reporter: once upon a time, this was the scene of epic battles, bloody entertainment,

and gladiatorial combat. today the calcium is nothing more than a photo opportunity, but not for long. in a tweet, italy's cultural minister championed the idea of replacing the coliseum's floor. the idea was floated by an italian archeologist who wrote in a magazine that the calcium should go back to being an arena. >> 6 million people come from all over the world to see it every year. so what do these people want to see in they want to see the place where a glad wait for fight took place. they see a hole now. so let's rebuild the floor and let's live the coliseum again. >> reporter: tourists like the
