Announcer this is nbc nightly news with lester holt reporting tonight from havana. Good evening. It has been a day rich in historic symbolism, brass tacks diplomacy. President obama, who reminded us today he was born the year of the bay of pigs invasion, met face to face on cuban soil with 84yearold president raul castro. Its their first meeting on cuban soil since diplomatic ties were reestablished. Afterwar afterwards, they emerged from what turned out to be a tense give and take with the press, ending with this awkward clasping of the hands, showing this relationship is still very much a work in progress. Our Andrea Mitchell was among the few called on at that press conference and joins me here now. Andrea, it was uncomfortable to watch at moments. Reporter it was uncomfortable, and its clear raul castro does not do press conferences. The two leaders agreed to disagree on big differences between the u. S. And cuba. Chiefly the u. S. Trade embargo, which president obama would like to end, and cubas treatment of dissents, testing the boundaries of a new relationship. It was a day of historic firsts. The handshake on cuban soil. Reporter the cuban military band playing the star spangled banner. This is a new day between our two countries. Reporter but raul castros criticism of the u. S. Trade embargo does not feel new. Translator we find it inconceivable that a government will not defend and ensure the right to health care, education, equal pay. After pressure from president obama, castro did take questions from the press, a rare occurrence. But when a cubanamerican reporter asked about cubas Political Prisoners give me a name or names. Reporter it is an issue overshadowing the visit. There were dramatic arrests of peaceful protests, the ladies in white. What signal does that send . If i engage frankly, clearly, stating what our beliefs are but also being clear that we cant force change on any particular country. Ultimately t has to come from within. President castro, what is the future of our two countries given the different definitions and the different interpretations of profound issues like democracy and human rights . Translator its not correct to ask me about Political Prisoners in general. Please give me the name of the political prisoner. And i think this is enough. Reporter the exchange fueling criticism by some dissidents, who say mr. Obama is normalizing relations too quickly. Antonio rodiles was detained briefly during sundays protest. The president s argument is if i come, if we talk, i can make progress. The American Government is giving too much to the regime, and the regime is telling clearly we are not going to move. Reporter clearly this is a relationship that is a work in progress, but there are new business deals. Today in the works for american firms here. Starwood today. Carnival cruise lines expected soon. A lot going on. The two will be at a state dinner later on. As events continue to unfold here, it is a very busy day in the race for president.

This is how were going to get our wealth back. Reporter outlining a noninterventionist platform, even questioning the countrys longstanding involvement in nato. I think we have to reconsider, keep nato but maybe we have to pay a lot less toward the nato itself. Its not a theory. Its proposal because we want friends. We want allies who are legally committed to come to each others selfdefense. The gop frontrunner addressing aipac tonight as his Campaign Continues to address ongoing violence at his rallies.

Eight months until november, this primary season already beginning to feel like a general election. Peter alexander, nbc news, washington. A manhunt is on for a newly named suspect allegedly linked to the paris terror attacks. Hes identified as a possible accomplice of salah abdeslam, who had been on the run for four months after the attacks. Now were getting a striking new look at the moment abdeslam was taken down last week. Nbcs keir simmons has more. Reporter stunning new images of the moment europes most wanted terrorist was captured. This is salah abdeslam, a senior belgian judicial source confirming to nbc news. The dramatic video shows his safehouse surrounded by police. He bursts out, runs down the street. Officers open fire. Shot in the leg, he is led away. And tonight police launching a new manhunt for another suspect, najim laachraoui, described as dangerous. His dna reportedly found during recent raids at locations housing explosives. Belgian officials admitting that despite arresting abdeslam, who helped drive suicide bombers to the paris city stadium, they are far from solving the puzzle of how isis pulled off the paris massacre. Abdeslam reportedly telling interrogators he was preparing more attacks. Filmed from a rooftop, the arrest of abdeslam fleeing from this doorway, shot here on the sidewalk, raises multiple questions. Why did it take four months to find him, and how many others are planning attacks . Intelligence failures before the paris attacks include allowing known isis operatives to return to europe, buy guns, and prepare explosives. The agencies that failed to track him now scrambling to find other isis recruits. To my mind, this does strike me as an intelligence failure. Abdeslam has been able to hide out for roughly four months in the middle of belgium. Reporter abdeslams lawyer says he is talking, but he is fighting extradition to france. Last time he was there, he was orchestrating a massacre. Lester. All right. Keir simmons tonight, thank you. Back in the u. S. To an investigation at Los Angeles International airport where a person thought to be a jetblue Flight Attendant took off running after being selected for a random secondary screening.

X. , neatly wrapped and stacked bricks of cocaine. 60 pounds of it confiscated after a Flight Attendant allegedly tried to get through a security checkpoint at terminal 4. Police say the suspect, not in uniform, flashed a jetblue id but was randomly selected for a secondary screening. Thats when she grabbed her bags and began running from the checkpoint. But she quickly dropped the bags, kicked off her gucci shoes, then ran down ang up escalator. Last seen outside the building running towards terminal 5. Experts say the fact she got away and the cocaine nearly got through are big red flags. Today its employees smuggling drugs. Tomorrow it could be an employee smuggling guns. Day after tomorrow, it could be employees smuggling a bomb. Reporter at l. A. X. , known crew members are not required to go through the same full screening that passengers do, but they can be pulled aside randomly. Fearing an Insider Threat like the one that may have brought down a russian jetliner over e gyp, Security Experts have long called for many moran dom of all airline and irport employees. Jetblue says its cooperating with investigators. Police are still looking for the suspect and whether she planned to meet anyone on the other side of the checkpoint. Meanwhile the l. A. X. Airport Police Union Says the case underscores while all airline employees should be required to go through full security. Lester. All right. To wild story. Thanks. There is a latebreaking development tonight in that major fight pitting apple against the fbi. Our justice correspondent Pete Williams has those details just coming in. Reporter lester the fbi says tonight it may have found a way to get into an iphone used by one of the San Bernardino attackers, a way of getting in without apples help. The government notified a federal judge late today that over the weekend, someone contacted the fbi with a possible way to unlock the phone without destroying its contents. For now, the fbi says it wants to test this idea to see whether it works. If it does, then it would drop its lawsuit against apple and abandon a Court Hearing set for tomorrow. The company has been aggressively fighting back against the fbis request that apple write special software that would disarm the phones security features and allow the fbi to use a computer to guess the pass code. The fbi tonight wont say who this idea came from or what it was, saying it wants to keep all that confidential for now. Lester. Nbcs Pete Williams, thanks. Still ahead tonight, banking on your potential. Were going to talk about the new way people are scoring loans and slashing their bills. Also superstar Serena Williams firing back after a tennis official lobs remarks that many call sexist. And welcome back to havana. Behind me the museum of the revolution. For people with bad credit or no credit, it can be tough to borrow money at an affordable rate. But theres a new kind of lending based more on your future potential than your Credit History. Nbcs Olivia Sterns explains. Reporter six months ago, dave collier ditched his job in the sagging oil industry and signed up for computer coding school. People always need apps to be built and managed and people who are can do that are going to be valuable. Reporter but the tuition put him 16,000 dd deeper in debt. Just 26, dave had more than 50,000 in loans and needed to refinance fast. Thats when he found upstart. I was able to consolidate 22,000 worth of credit card debt, cut my rate in half, and accelerate my timeline for getting out of debt by about three years. Reporter in fact, upstart brought daves right from as high as 19 to just 8 , saving him for man 5 now dollars. Its the brainchild of dave gerard, his goal to help people just like dave get cheaper credit. Were in the business of seeing signals about a person that others dont see. Reporter instead of focusing on your Credit History or your fico score, upstart bets on your future. Fico is inherently backward looking. What youve done with credit in the past, we like to view it as identifying somebodys potential, where theyre going. Reporter upstart asks where did you go to school, what did you study, how much will you make in the future, and ask this a reliable career . Upstart is one of a growing number of companies shaking up the lending industry. But experts warn these new Business Models arent proven. The jury is going to be out until were in a recessionary environment and defaults go up. Thats where you can really see what form of lending was worth the risk and which was not. Reporter risk dave gerard is willing to shoulder while dave collier is looking forward to the future. Olivia sterns, nbc news, san antonio.

Reporter moore told reporters male stars have carried the sport. If i was a lady player, id go down every night on my knees and thank god that Roger Federer and rafa nadal. The states top female player quickly took the offense. Women have come a long way, and we shouldnt have to drop to our knees at any point.
