0 has been undergoing constant revision since 9/11 when it was discovered that some of the hijackers who came here to attend flight school or dropped out or never even showed up. the government began to get better tracking of students, when they come here on a student visa, are they in school? are they staying in school to maintain the validity of their visas? now they're trying to make that information almost real-time to the border patrol officers. because one of the friends of dzhokhar, when he came back into the country in the interim, while he had been gone, he had stopped attending classes, his visa was no longer valid. but he was admitted nonetheless and that's what they're trying now to tighten up even further, andrea. >> pete williams, thanks very much. president obama today about to leave mexico for costa rica. the second leg of his latin american trip. he promised a university audience in mexico city, he's going to fight for immigration reform. >> we also know that as nation of immigrants, the immigration system we have in the united states right now doesn't reflect our values. that's one of the reasons i acted to lift the shadow of deportation from what we call the dreamers. young people brought to the united states as children. and that's why i'm working with our congress it pass common-sense immigration reform this year. and i am optimistic that after years of trying, we are going to get it done this year. i'm absolutely convinced of it. >> joining me for our daily fix, jose diaz balard of telemundo and latin council on foreign relations. >> how did the trip go so far? this is the big trip, you've got a new mexican president, a lot of issues, immigration, guns. and the economic ties between our two countries. >> good afternoon, andrea, the trip went extremely well this is the fourth visit by president obama, the fourth time since his re-election. the first time here in mexico he meets with the current president, enrique p he enieneto. there's been some interesting friction, recently. the new government of mexico has decided to change some of the parameters and the ways that for example, american d.e.a. and c.i.a. communicate with their counterparts here in mexico. they're changing the way they communicate. they're streamlining it according to the mexican government. some in washington are concerned that maybe they're closing some of the doors available for communication between agencies on both sides of the border. yesterday the president met with president pena nieto. in a joint press conference they were clear both sides are on the same page as far as the fight against narco terrorism and also immigration. this san important issue for the united states, as we know, and also for mexico. >> and jose, i know that you're going to be, we're watching live pictures of the president about to leave mexico city for costa rica. jose you're going to be interviewing the president in costa rica, and we're going to see that on telemundo on monday, i believe. i wanted to play a little bit of what the president is saying to the students about guns, this has been a constant irritant for the mexicans about the guns coming across the border. let's watch. >> we also recognize that most of the guns used to commit violence here in mexico come from the united states. in america, our constitution guarantees our individual right to bear arms, as president, i swore an oath to uphold that right and i always will. but at the same time, as i've said in the united states, i will continue to do everything in my power to pass common-sense reforms that keep guns out of the hands of criminals and dangerous people. >> shannon o'neill, the president can say that in mexico city, but so far, he has, as we know, not been able to even get the background checks bill through. and while there's an effort now by joe manchin, pat toomey to bring it back and try to change it enough so that people can change their votes credibly, it's a real longshot. >> well it's interesting, two issues that came up as you mentioned. one are gun control and one are immigration. and while both of those are incredibly important for mexico and the population there, and the security efforts, they're both domestic issues and the mexican government response from the mexican president, was to say we wish the president well in these efforts that he has, but we're not going to enter into these debates. we do understand the domestic politics in the united states around these issues, gun control and immigration are incredibly important and very complicated. >> i want to ask you and jose also about the bigger picture. from the mexican standpoint from the standpoint of latin america, which has really been ignored by the administration as we've fought two wars and dealt with the european fiscal crisis. mexico has been stronger economically and at the same time we haven't really paid enough attention to what's happening south of our border. shannon? >> well one of the reasons the president went now, and the really big focus we saw was on the economic issues. and it's because the united states and mexico, they recognize how important the ties are between the two nations. we see half a trillion dollars worth of goods going back and forth. making each one of the most important trading partners, but more important than that is what is going back and forth across the u.s./mexico border. this has changed over the last 15 or 20 years. today it's not finished goods, it's pieces and parts. so what that means is that u.s. companies, but as important, u.s. workers depend on what's happening down in nextco. that was really the big part of the conversation, how do you deepen those commercial ties. >> jose, from your perspective, what do you think the mexican leadership, the new mexicans want to hear. >> this is not the first administration that kind of -- yeah, i was going to tell you, this is not the first administration that could ignore latin america. it's pretty much part and parcel of american history that latin america is ignored until something bad happens and they have to deal with it. the fact is and shannon was talking about this, there are parts of mexico that that are booming economically. leon, merchandising and auto industry and the border areas you have car companies and the united states that has, that have in mexico, the issue of immigration is important and the issue of the economy is important and the issue of drugs is important. the president today in his speech to young people talked about how he's aware that the united states also has a responsibility with the blood that has been shed and is continued to be shed here in mexico. because american consumers want illegal drugs. it's no coincidence that the drug cartels are based in the northern parts of the mexico. because they want to be as close to their clients as possible. every line of cocaine that is snorted up somebody's nose in the united states is dripped in the blood of innocent people here in mexico and in other latin american countries. because of that demand. and it was very important that the president mention that today. because it all goes hand in hand. the economy, immigration, and drugs and arms. 80% plus of the weapons that are caught in this country come from the united states and they're used in horrendous acts of violence. so the relationship between the united states and mexico? yeah, it's economic and it has a lot to do with immigration. but there's also responsibilities that need to be outlined and need to be dealt with. >> thank you for that. jose diaz-balart and shannon o'malley from new york. southern california, what a disaster, fire crews fighting wildfires covering 15 miles of land. winds are a major problem for firefighters trying to protect homes in the ventura county and camarillo county areas. mike tiabbi spoke with residents. >> if these trees go up, we're in trouble. >> you're in trouble, the flames are here, ten yards away. >> give me back my hose,ky put it out again. ose tens of thousands of dollars on their 401(k) to hidden fees. is that what you're looking for, like a hidden fee in your giant mom bag?
