practical, and you do what is needed to be done and what is in front of you, and one of the things that is important for the united states or for canada, or for any leading power in the world, is to live up to its commitments, and to provide continuing momentum on efforts even if they didn't start under your administration. so there are a whole host of initiatives that began under the bush administration. some that i was very enthusiastic about, like pep-far that has saved millions of lives and prevented hiv aids or provided vital drugs to those already infected with hiv aids in africa and other parts of the

world, something that president bush deserves enormous credit for, you know, we continued that. but there were also areas when i was outside the government i questioned how they were approaching it. i might have tweaked it. i might say to my foreign policy partners, look, we have a problem of doing it this way, but here is a suggestion for how we can do the same thing or meet your interests in a slightly different way. but -- but you are always concerned about making sure that the credibility of the united states is sustained, or the credibility of canada is sustained, which is why when there's turnover in governments, you know, the work that has been done continues, and particularly when you have a close friendship and relationship with a partner like canada, it's not as if work we're doing on the arctic, or on

entry and exit visas vanishes when the next president comes in. of course i intend to make sure the next president who comes in agrees with me on everything, but just in case that doesn't happen, the u.s. canadian relationship will be fine. all right. thank you everybody. thank you. >> you have been listening to the president of the united states with the prime minister of canada, the newly elected prime minister, justin trudeau, 44 years old. trudeau being the newly elected prime minister and former ski slope worker, boxer, and son of the former prime minister pierre trudeau. it was the first meeting between the united states president and the canadian prime minister in 19 years. both men talking about their common bond a and talking a lot about trade, but they also spent

some time talking about making it easier for canadians and americans to travel between the two countries. and one point during the conversation it turned to hockey, trudeau saying it was a sore point the president asking where the stanley cup is right now, joking about the fact that it resides in his hometown of chicago. mike viqueira was there. he is at the white house for us right now. and mike most of the questions were dealing with the question climate change, and cutting carbon emissions. saying that things will stay the change with regard to climate change. >> reporter: right, the american press more concerned with the raging politics going on right now. and there's no question that the impending election is casting a shadow over the rose garden here today. first time in 19 years a

canadian prime minister has been here for a state visit. all of the pump and circumstance connected with that. but the president taking time for a long-sort of public meditation on the state of the republican party in response to a question. yes, he did get his first question from the american press was about the supreme court nomination. he said he would be nominating someone it appears to be in short order here, someone that he assures everyone will be eminently qualified. but then he was asked about the state of the republican party, and whether he is somehow responsible for the tone of american politics that we have seen with theed a -- advent of donald trump and the other candidates. here is what he had to say. >> the tone of that politics, which i have not contributed to.

i don't think i was the one to prompt questions about my birth certificate, for example. i don't remember saying, hey, why don't you ask me about that? [ laughter ] >> you know why don't you, you know, question whether i'm american or whether i'm loyal or whether i have america's best interests at heart? those aren't things that were prompted by any actions of mine. and so what you are seeing within the republican party is -- is to some degree all of those efforts over a course of time creating an environment where somebody like a donald trump can thrive. >> reporter: so all during that, the prime minister waiting patiently, but to give you an illustration again of how the

impending election is effecting what is being said in this meeting, one of the agreements was this agreement on reducing -- or at least the goal of reducing methane emissions. obviously something that is shared between these two leaders, and that in and of itself a break from trudeau's predecessor, stephen harper who wasn't as seen on reducing global emissions. trudeau really taking up that mantle, this young charismatic leader of 44 years old, for this agreement. even with the obama administration goes forward with the plans, the calendar is against him. because it is certain to last beyond november and the inauguration in january, so a lot riding on this election, whether or not this agreement that was announced today will ever come to fruition, del. >> and mike, there were so many

questions about what happens if and when there is the changing of that guard at the white house if it changes from democrat to republican? specifically with the issue of trade agreements. in other words will the incoming administration well cam a trade agreement negotiated by the obama administration. and there seemed to be push back saying once you get into the white house you have to make decisions that are good for america, but there were no guarantees. >> reporter: and there is a sea change that evidencely is underway here with regard to trade. obviously this is something a democrat has joined hand with establishment republicans, if you will, on capitol hill and pushed through. but what we're seeing now is the advent of bernie sanders, pushing hillary clinton towards a stance that is perhaps more

anti-trade that she is comfortable with. she of course has changed her view on the big trans-pacific partnership that the obama administration have pushed for so long. now it is before congress, and it is going absolutely nowhere. if that remains that will be a bitter disappointment and big set back in terms of the trade policy and trade agenda, as well as to the american and canadian business community. so trudeau is saying what he needs to say, saying no matter who is elected, we expected to have a good relationship with the united states. they are so intertwined, you heard the figure, $2.5 billion crossing the boarder in goods and services each and every day.

cooperation on a whole host of areas, you name it down the line. so obviously a close relationship, nothing is going to shake that, but clearly, again, american politics casting a shadow over this visit. >> and they were talk about syria and isil. i want to play one of the comments that was made earlier, and get your thoughts on the back end. let's take a listen. >> as nato allies, we're united in the fight against isil, stepping up intelligence efforts in the region, and providing critical humanitarian support. we're working closely together to prevent the flow of foreign fighters, and we agreed to share more information including information on the no-fly list. >> so mike, it would appear all

is well. >> and a month ago he announced we would be pulling canadian planes out of the fight against isil. but again as the president said and prime minister trudeau pointed out, canada also stepping up its role in ooer r air -- other areas. so whereas that is a potential source of friction, or could have been, that seems to have been diffused now, del. >> mike thank you very much. campaign 2016, democratics and republicans coming up. and we'll talk about more concerns about lead in drinking water. this time it's in new jersey. and a state of emergency in louisiana after parts of that state receiving more than a foot of rain. more could be on the way.

there's fallout that shows hillary clinton has a sizable lead. a survey showing that hillary clinton has nearly a 2-1 margin over bernie sanders. it surveyed voters in the state of ohio, and clinton is ahead there. jonathan betz, live for us in

miami. they debated last night, their eighth time. a different border this time than the one we just got done talking about. >> yeah, without question, del, immigration if not the topic of concern for many people last night, it's a big issue here in florida and across the state, and it was a point with resaw them clashing. clinton going hard after sanders over his refusal to back a 2007 immigration overhaul plan, repeatedly criticizing him during the debate last night. sanders defending himself saying the program would not have been good to guest workers, comparing it to something akin to slavery. and they also focused on deportation. in florida there are a lot of people who are very upset at the

number of people that have been deported under president obama. so the moderators tried to press the candidates on whether they would support children. hillary clinton tried to give a more nuanced answer before finally saying this. >> i do not want to deport children or families. i would prioritize people to deport. >> i happen to agree on president obama on many, many issues. he is wrong on this issue of deportation. i disagree with him on that. [ cheers and applause ] >> so to answer your question, no, i will not deport children from the united states. >> reporter: so both offering the same answer but taking different paths to get to that answer. as you mentioned this was the eighth and what could be the

final democratic debate this year. now many in florida are turning their attention to the republicans who will also hold a debate in miami. >> what do they about where the democrats standing in the state of florida. >> reporter: there was a poll released yesterday you mentioned earlier, that came out ahead of this debate. she leads by 30 percentage points. so she goes into the primary with a very, very significant lead. >> jonathan thank you very much. a brief moment of violence at a donald trump rally in north carolina. take a look. a protester punched by what appears to be a trump supporter. jones says security holding him down after he was hit. trumps critics have said his

comments towards protesters could incite violence. as you heard jonathan say it is debate number 12 tonight. the polls in florida have trump with a double-digit lead over his competition. in that could humiliate martin scorsese in his home state. >> reporter: it has been a tough week for donald trump's rivals and republican leaders trying to change the trajectory of this race. trump has divisive victories this week. >> we're going to win so much. we're going to win with our military. we're going to win with everything. we're going to win so much, that you are going to say, mr. president, we're winning too much. it's too much. >> reporter: texas senator, ted cruz is trying to broaden his appeal from evangelicals.

>> we need a real conservative who will provide real conservative solutions in people's lives. that is the only way we beat donald trump, and that is the only way we are going to beat hillary clinton, and ted is the man to do it. >> reporter: the campaign focus now shifts to a group of delegate-rich states, one of those is florida, marco rubio's home state. he has had a string of poor showings in recent weeks. but the senator remains bullish on his chances. >> i will be on that ballot on tuesday. i will complain as long as hard as it takes. we are going to the white house, and we are going to win the nomination. >> reporter: rubio said he regrets his personal attacks on trump. >> in terms of personal stuff, yeah. that's not something i'm entirely proud of. my kids were embarrassed by it, and if i had to do it again, i

wouldn't. >> reporter: donors are expressing concerns about his fate in florida. the senate judiciary committee conducting a full blown debate on whether to hold hearings on a obama nominee. >> regardless of what some are willing to admit publicly, everybody knows any nominee submitted in the middle of this presidential campaign isn't getting confirmed. everybody knows that. the white house knows it. senate democrats know it. >> president obama said to be looking at five possible nominees, all are federal judges. all of them serving in washington, d.c. paul is on the bench in san francisco, jane kelley is from iowa. senate republicans as you just heard have vowed not to even

consider that nomination to replace antonin scalia. >> i'm confident that whoever i select among fair-minded people will be viewed as an imminently qualified person, and it will then be up to senate republicans to decide whether they want to follow the constitution. >> reporter: the president going on to tell reporters that he hopes cooler heads will prevail because of what is at stake. when we come back, up next we'll talk about the people act that is making some people very nervous. ♪
