>> miller: history in havana tonight, as president obama arrives in cuba. we're on the ground for his landmark visit. >> he's a disgusting guy. another wild weeken another wild weekend for the trump campaign ahead of tuesday's voting contests in the west. a protester is punched. trump defends his campaign manager in a separate incident. spring break crackdowns are forcing the party crowds to beach hop. where are they headed next? and, a bird's eye view to a baby eaglet's birth. this nest is getting crowded. captioning sponsored by cbs this is the "cbs evening news." >> miller: good evening, i'm michelle miller, with the

western edition of the broadcast. president barack obama stepped off air force one and into the history books today as the first sitting american president to visit cuba in 88 years. the president arrived in havana with first lady michelle obama, and their daughters, sasha and malia, after touching down, the president tweeted "que bola, cuba?" or "what's up, cuba?" and said he's looking forward to meeting the cuban people. margaret brennan is travelling with the president. >> reporter: today barack obama became the first u.s. president to walk on cuban soil since 1928, when calvin coolidge arrived aboard a warship. president obama brought another symbol of american power: a delegation of corporate leaders, including the c.e.o. of xerox, and executives from companies like marriott and starwood, which just struck a deal to become the first american hotel

operator in havana in nearly 60 years. they will tap a market long out of reach due to the ongoing trade embargo that cut off communist cuba during the cold war. scholar peter kornbluh, author of "backchannel to cuba," said the island is ripe for investment. >> they see a market that is really ready for u.s. companies and the professionalism and the infrastructure and the resources that u.s. companies can bring. they see a potential tourist hotspot that from here to eternity. >> reporter: when the castros accepted the 2014 offer to normalize relations, they appeared willing to test the benefits of capitalism. since then, the u.s. has approved over $4 billion worth of business between the former foes, loosened the travel ban, restarted direct mail service, and now allows cubans to open bank accounts and earn salaries, a step that means athletes no longer have to defect to the u.s. to legally work there. while the cuban public is enthusiastic about the president's outreach, the castro

government has been slow to make many of the changes that the administration asked for. >> relations with the united states have to overcome great obstacles of history and there still is this suspicion that the normalization process is a trojan horse to kill the cuban revolution with love rather than with aggression. >> reporter: and in many ways that is the strategy: the obama administration thinks increased financial opportunity will lead to irreversible change in this authoritarian state. >> miller: france is working to bring a suspect in the paris attacks back from belgium, where he was arrested friday, and may have been planning new attacks. as charlie d'agata reports, investigators are revealing more about salah abdeslam's alleged role in the murders last year of 130 people. >> reporter: it turns out salah abdeslam wasn't just a driver.

he was a key operative in the paris massacre orchestrated directly by isis. french prosecutor francois molins has accused the 26-year- old of being the chief logistics man for the attacks. so far the investigation has turned up that abdeslam purchased 12 detonators and explosive materials for the suicide vests, rented safe houses for fellow attackers, and had planned to blow himself up in the stade de france, but lost the nerve and backed out. this is thought to show the arrest of abdeslam on friday, wounded in the raid by belgian anti-terror police. he's now fighting extradition to france. sven mary, abdeslam's lawyer, is threatening to sue the french prosecutor for breaching his clients confidentiality. i understand client confidentiality, but is he denying involvement? >> no. he doesn't deny that he was in paris. but, there are a lot of matters in this fight.

>> reporter: in a raid earlier this week, anti-terror police found a stash of weapons, and abdeslam's fingerprints, leading belgian authorities to believe he may have been planning another attack. the belgian government has been praising its anti-terror forces for capturing abdeslam alive, but local leaders like francois shepmans, mayor of molenbeek, face uncomfortable questions as how a manhunt that stretched to syria, ended just a few blocks from where he grew up. i'm sitting here in america and i'm wondering what took you so long to find this guy, he's right there in your neighborhood? >> well, its a city here. its one million people. you think you can find easily terrorist here in a big city? >> reporter: now he's a resident here, a high security prison in bruges. it's got a section for high profile prisoners with specially trained guards.

cells have double doors and any furniture or equipment is bolted to the floor. >> miller: charlie d'agata, thank you. violence erupted again this weekend at a donald trump campaign rally. as mark albert reports, the republican front-runner is defending his supporters, and his campaign manager. >> get them out of here! >> reporter: moments after donald trump denounced a demonstrator wearing k.k.k. headgear at a rally in tucson, a second person being led out just ahead of them was attacked. punched, kicked, and pummeled before the attacker calmly turned around to be arrested. police had to call in reinforcements, using 150 officers in all. but trump criticized their response. >> security at the arena, the police were a little bit lax. >> reporter: trump's campaign manager, corey lewandowski also confronted a protester.

trump later said lewandowski "didn't touch" the man. and praised his top operative. >> i give him credit for having spirit. he wanted them to take down those horrible profanity-laced signs. >> reporter: g.o.p. chairman reince priebus was asked on cnn about the unusual sight of a campaign manager personally confronting demonstrators. >> getting involved in violence, confrontation, is not the answer. you leave this up to the professionals: police, secret service. >> reporter: earlier saturday, protesters shut down the main road to a trump rally near phoenix. >> donald trump, go away! >> reporter: while in new york city, police used pepper spray and arrested two during a protest march to trump tower. >> economic populism, xenophobia, race-baiting, and religious bigotry are the stools that he has formed. that is his campaign. >> reporter: senator lindsey graham said trump has "divided" his party. >> we're about to nominate the one person that not only would lose in 2016, but would destroy the party for decades to come. i'd rather lose without trump than try to win with him. >> reporter: donald trump is scheduled to meet with party leaders tomorrow here in washington. before he takes the stage at the annual convention of the american israel public affairs committee.

his rivals ted cruz and john kasich will also address aipac monday, along with hillary clinton. michelle? >> miller: the road to the presidential nomination runs through three western states this tuesday. republicans and democrats have primaries in arizona and caucuses in utah. and there's a democratic caucus in idaho. the big prize is arizona, especially for republicans, where the winner takes all 58 delegates. here's danielle nottingham. we're going to tbimed >> reporter: immigration was at the center of donald trump's weekend blitz through arizona. >> illegal immigration is gonna stop, it's dangerous, it's terrible. >> reporter: trump is hoping his hard line on immigration will resonate with voters. democratic front runner hillary clinton is already drawing the battle lines, running an ad in arizona where she comforts a young girl worried about deportation. >> i'll do the worrying. i'll do everything i can to help, okay?

>> reporter: bernie sanders, campaigning this week along the arizona border with mexico, says he's also sensitive to the plight of immigrants. for republicans, the biggest battle now is a philosophical one. trump's opponents, senator ted cruz and governor john kasich, are doubling down on their attacks, saying one of them should lead the charge to deny trump the nomination, and the other should drop out. kasich says, it won't be him. >> nobody is calling me directly and asking me to drop out. why don't they drop >> reporter: cruz, campaigning in utah, says he's not going anywhere. >> a vote for john kasich is vote for donald trump. >> reporte >> reporter: if they split the vote, the man they hope to beat, could benefit the most. danielle nottingham, cbs news, los angeles. >> miller: the investigation continues into a deadly jet crash in russia. officials say they have the blackbox and voice data

recorders, but they're badly damaged from friday's crash. fly-dubai flight 981 went down in strong winds, killing all 62 people on board. the marine killed in iraq yesterday has been identified, be lewis cardoon temecula, pope francis made his debut on instagram, just in time for palm sunday. he already has over 1.4 million followers. >> reporter: pope francis abandoned his prepared palm sunday text to compare what he called "indifference" to migrants and refugees arriving in europe to those who washed their hands of jesus ahead of his crucifixion. making use of the wider audience the special day provided is typical francis, and this weekend he embraced another way to reach out-- instagram-- a sign-up he called "beginning a new journey." he picked up one million followers in 12 hours

the pope already tweets in nine languages, including latin, to more than 25 million followers. he doesn't type his own tweets, usually quotes from his speeches, but approves every one. his instagram pictures will be chosen by a senior media adviser, according to deputy vatican spokesman greg burke. >> you're not going to see pope francis with a selfie stick here saying welcome to my home. but he knows that can be important, he knows the importance of getting the message out. >> reporter: francis is number two behind president obama in twitter followers. there's a certain irony to the leader of an institution that generally embraces change at a glacial pace having an online following that would be the answer to the most fervent prayers of those celebrities who measure their worth by social media hits. and this for a man who labeled social media both "mental pollution" and "a gift of god." it's one of the "great enigmas" of this pope, father anthony figueredo says: >> the way he acts, the way he talks the way he reaches out to

people, is a great, great change, and the papacy will never be the same. >> reporter: but he still hasn't made a major impact on church reform, or the sex abuse scandal, catholic writer robert mickens says. >> i think he's been given a pass because he's been such a wonderful inspiring figure. but we're now in the fourth year of the pontificate and i think he's got to address this or it could very much damage his pontificate. >> reporter: and it will take more than the common touch and record-breaking numbers on social media. allen pizzey, cbs news, vatican city. >> miller: coming up: spring break crackdowns have party- towns going from boom to bust. and, the formula one season gets off to a frightening start, when the "cbs evening news" continues.

>> miller: spring break brings big business to beach towns all across the south.

but it also brings crime, so many communities are cracking down. as jamie yuccas reports, new laws designed to stop the party are just forcing it to move elsewhere. >> reporter: the sounds of young people partying and opening beers on the beach are now silenced in gulf shores, alabama. this weekend the city enacted an emergency order banning alcohol on beaches through april 17 after more than 600 arrests since march 5. police lieutenant bill cowan: >> most of the arrest come down to public intoxication, minor in possession of alcohol are our two biggest categories of arrests. >> reporter: but college students like hannah hicks and christian gerring from texas a&m think the police are being overly aggressive. >> somebody was videotaping in a cops face and he said you are interfering with an arrest so he like hooked her up. it's stupid reasons. >> i know we're being drunk and we are on spring break, but we're still adults we're in college we know what we're doing and they act like we are children.

>> reporter: gulf shores officials believe they became the hot spot after word spread on social media that nearby panama city, florida, banned alcohol from its beaches last june. the new ban in gulf shores is raising concerns that students could now move the party a few miles down to orange beach, alabama, which is dealing with an 800% increase of its own in arrests this spring break. dan rowe oversees tourism and conventions for panama city beach, florida: >> the city leaders were compelled to make some legislation changes because of incidences of young people behaving badly. >> reporter: last year, an unconscious woman was allegedly gang-raped while onlookers did nothing. a shooting wounded seven, and more than 1,000 were arrested. rowe says there are less problems, but there is also less money. >> if the college kids aren't here, the businesses that have catered to that college spring break market are the ones really taking the brunt of it this year. >> reporter: like sparky sparkman, who owns spinnaker.

his beachside bar has become a ghost town with business down 80 to 90 percent. >> it's gone. and you know what they say about something, once it's gone, yeah it really is tough to get back. >> reporter: in all, panama city beach enacted at least 20 new ordinances to crack down on bad behavior, and like gulf shores, will review the alcohol ban on their beaches before next march. michelle? >> miller: up next: we break down the trade deals that are a hot topic on the campaign trail.

>> miller: u.s. trade policy has been a hot button issue on the campaign trail, with candidates from both sides trashing deals that they say cost america jobs. >> nafta, supported by the secretary, cost us 800,000 jobs nationwide. >> i will say trade deals are absolutely killing our country. >> miller: the question is: are

international trade deals helping or hurting the american worker? here's cbs news business analyst jill schlesinger. which is it? >> a little bit of both. the north american free trade agreement from 1994, the one that bernie sanders said costs 800,000 jobs, prob >> a little bit of both. the north american free trade agreement from 1994, the one that bernie sanders said costs 800,000 jobs probably didn't. it was probably a wash according to economists but china's entry into the world trade organization was a game changer. if we look at the exporting and manufacturing here in the u.s. since then it's down by nine percent. china's exports and manufacturing up by 12%. but remember, overall, us consumers have been able to buy goods a lot cheaper since all these trade deals. >> miller: so trade shuffles the deck, who are the real winners and losers here? >> well, i think that manufacturing has been a loser but we should note manufacturing jobs actually peaked in 1979, so that's 15 years before nafta. what's really changed the game? technology. automation. and when we look at those sectors around technology we saw technology up 30% since 2003.

and we should also note one big winner, the world because we see millions of people lifted out of poverty. >> miller: what about the folks back home? how do you help those people who've lost their jobs? >> by not ripping up trade agreements. trade wars are terrible for economies but by really spending some money on retraining and offering financial assistance in the form probably of tax credits. that's probably the best solution. >> miller: all right, cbs news business analyst jill schlesinger, thanks for being with us. still ahead: a flying horse with a harrowing story.

>> miller: there was a frightening crash today, at a formula one event in australia. driver fernando alonso, totally at the mercy of gravity, after clipping another car. amazingly, he walked away from this. he says he feels lucky to be alive. if you were in los angeles yesterday, you might have seen a flying horse, or at least

dangling from a helicopter. the horse had fallen into a ravine and rescue workers figured this was the best way to get it out. the horse was a little disoriented, but not hurt. new video shows something perhaps never before seen by human eyes. a blue whale nursing its calf. or at least that's what scientists believe is happening here. the images were taken off new zealand. coming up: while many were sleeping, the un-blinking "eagle cam" made the catch of the day.

>> miller: we end tonight with some new beginnings. here in the east, spring arrived at 12:30 a.m. shortly after that, there was another noteworthy arrival on washington, d.c.'s eagle cam. jericka duncan has the bird's eye view. >> reporter: just after 3:00 this morning, the eaglet known as d.c. 3, finally appeared on a live web cam. its parents immediately scrounged up some food for the new baby and its two day old

sibling. social media is now celebrating both births. dr. jill biden wrote: "congratulations to "mr. president" and "the first lady" on the arrival of two eaglets!" the proud parents are known as mr. president and the first lady because they're the first mating pair to nest in d.c.'s national arboretum, in nearly 70 years. jen keefe is among the many who couldn't turn away. >> why do you think people are so obsessed with this webcam? i think it's the american bald eagle, that bird is our national symbol, and it's funny watching animals for hours at time is a growing phenomenon. last year, millions watched panda bear mei xiang give birth to twin pandas, only the third set ever born in the united states. at the national arboretum, a message below the live eagle

cam, warns viewers that you could see anything, from sibling rivarly to predators. >> i think with all the political turmoil going on, these little eaglets are something we can agree on. >> reporter: democrat or republican. >> democrat or republican, independent, socialist, trump, whoever you are, i think we can all agree on that we can get behind the eaglets. >> reporter: in a few weeks the public will come up with names for the eaglets, because to the many who watched, this family is part of theirs too. jericka duncan cbs news, new york. >> miller: that's the "cbs evening news" for tonight. later on cbs: "60 minutes." i'm michelle miller in new york. thank you for joining us, and good night. captioning sponsored by cbs captioned by media access group at wgbh access.wgbh.org
