Nightly news begins right now. Announcer from nbc news World Headquarters in new york, this is nbc nightly news with lester holt. Good evening. One camp wants to beat donald trump. The other just wants to stop him. Ted cruz and the stop Trump Movement are each building their hopes on wisconsin where polls show cruz leading trump ahead of tomorrows primary, but it will take more than a trump loss by itself to sidetrack his march to the nomination which is why both efforts are tonight counting on a surge of momentum to level the Playing Field going forward. It happens to be virtually the same strategy playing out on the democratic side with Bernie Sanders trying to turn the tables on Hillary Clinton. We have it all covered starting with nbcs Hallie Jackson who is in wisconsin this evening. Hallie, good evening. Reporter good evening, lester. Donald trump has thousands of people packing his rallies here in wisconsin, but hell need more support than that to avoid a loss to ted cruz, but its not trump who has to win in this state. Its the never Trump Movement needing a victory now more than ever. Closing in fast, the wisconsin finish line less than 24 hours away, the last push through a state that matters more than anyone thought it would, not just for its 42 delegates but for the momentum it could give the stop Trump Movement. They realize that donald screams and yells a lot but he has no solutions. Reporter its a dramatic reversal from only a month ago when this looked like trump country, blue collar, more moderate, an open primary, and then since then ted cruz has surged more than 20 points fueled by the stop Trump Movement making milwaukee growero led by a group of conservative talk show hosts like charlie sykes. This is not a conservative candidate. Its a clown car and the rhetoric that works elsewhere does not work in a state like wisconsin. Reporter why tomorrow is the best shot for antitrump groups to show that they can stop him as several strategists tell nbc news that new ads are on the way beyond the badger state. 42 delegates in wisconsin are critical to stopping donald trump. Reporter but a win here would prove trump is teflon, really after his toughest week yet, battling back criticism from economists who are wrong to warn that were headed for a crash. What i said is were going into a massive recession, but i also say if im president thats not going to happen. Reporter plus a revealing new profile claiming he wears a bulletproof vest sometimes, even as he comes under fire for rallies that can turn violent. He says he can start acting president ial whenever he wants. So far its the same trump on the trail. New yorkers are like in a. Reporter and thats fine with linda hanson who says shes sticking with him no matter what. Youll never ever, ever change me. Im pulling for him. Reporter Hallie Jackson, nbc news, milwaukee. Reporter im Kristen Welker traveling with the clinton campaign, its a question of math versus momentum. Bernie sanders is looking for a win in wisconsin but anything short of a blowout wouldnt do much to dent Hillary Clintons nearly unsurmountable delegate lead. I want Hillary Clinton more nervous than she already is. Reporter sanders touting his slim lead in wisconsin today where his message is resonating with throngs of progressive voters. On the heels of winning five States Sanders is gaining momentum, the race increasingly combative. Shes already under a lot of pressure so dont tell her this, but i think we win here, we win in new york state, were on our way to the white house. Reporter the reality, clinton is ahead by double digits on her home turf of new york but sanders is slowly narrowing the gap and campaigning here today as the state passed a minimum wage increase, clinton took a familiar if veiled swipe at sanders again painting his policies as unrealistic. Feelings have to be matched with politics. Reporter another reality check. His campaign is acknowledging to the New York Times early missteps which are now creating a drag on the campaign, saying sanders initially failed to aggressively challenge clinton. Late tonight sanders aides telling nbc news the article isnt a sign they are throwing in the towel. We think theres a path to the nomination. Reporter now the only way sanders can make a play for the top spot, start winning big, really big. A big win for Sanders Msnbc that not only does he have momentum but that he gets more of the delegates that they have been looking for. Reporter as clinton campaigns here in albany, her campaign is releasing a new memo touting her, quote, unsurmountable lead, a sign that they are trying to project confidence as she faces tough odds in wisconsin tomorrow. Lester . Kristen welker, thanks. Tonight, two weeks into spring and millions across the country is wondering where is it .

The ntsb is reviewing tape of the moment of impact, but investigators say they are no closer to determining what or who is to blame. Nbcs tom costello has the latest. Reporter south of philly today, a slow ride down the same tracks that were the scene of yesterdays deadly crash. The ntsb said this afternoon cameras on the amtrak train showed Maintenance Equipment sitting on two sets of tracks just before the crash.

Reporter investigators say they dont know why the equipment was there and whether there was some breakdown in communication. Palmetto train 89 from new york was headed south to georgia and had just passed philly. As it went through chest, p. A. , the amtrak backhoe was sitting right in the trains path.

They all circle and lead to one person, in this case vladimir putin. I dont think well ever see Vladimir Putins name on an offshore company or an offshore bank account, but i think this is probably as close as youll ever get. Reporter putin is believed by u. S. Intelligence to be one of the worlds richest men.

Another major player in the documents, mikhail lessin, the former head of putins propaganda operation was found dead in this washington, d. C. Hotel in november, bludgeoned to death. He would have been able to speak about that but not anymore. Reporter protests tonight in iceland where the Prime Minister accused of hiding money denied wrongdoing but walked out of an interview when asked about it. Many of these offshore companies are legal and putins spokesperson called the investigation an attack against russia. I think points press barons will now work overtime to make sure this story is buried. Reporter the Law Firm Says it only sets up the companies and is not responsible for how they are run. No comment from jackie chan, but the justice and treasury departments are already poring through these documents. Lester . Andrea mitchell, thanks.

Reporter for years some doctors thought these complaints might be psychosomatic, all in their heads, but a new Study Concludes that the pain is real.

Reporter the good news is there is potential relief. The drug has been approved. Reporter already two cholesterollowering drugs have been approved by the fda. One repatha cuts levels of bad cholesterol by more than half, according to the new study. Diane says the medication changed her life.

Reporter but the bad news is they are expensive, about 14,000 a year, and only fdaapproved for people with hereditary high cholesterol.

On the very day a deal was announced that Alaska Airlines is buying Virgin America for 2. 6 billion, Virgin America took the top spot in this years Airline Quality ranking which is based on online performance, customer complaints and baggage. At the bottom were frontier, envoy air and spirit. Meantime, United Airlines has removed a Flight Attendant from duty after she apparently inflated the emergency slide when their plane arrived in houston this afternoon. United says there was never an emergency on board, and as nbcs Miguel Almaguer reports, this isnt the first time an incident like this has happened. United flight 1246 had just reached the gate in houston when the airline says the Flight Attendant intentionally deployed the evacuation slide even though there was no emergency. 159 passengers were on board the flight from sacramento with a crew of six, including the Flight Attendant who for unknown reasons inflated the chute. We hold our employees to the highest standards, united says. This unsafe behavior is unacceptable and does not represent the more than 20,000 Flight Attendants who ensure the safety of our customers. Its not the first time an escape slide has been deployed. In 2010 a fedup jetblue Flight Attendant let loose on passengers over the planes intercom and pulled the chutes emergency lever before later being arrested. Steve slater did a year probation on a charge of criminal mischief. Back in houston, no injuries but questions. Tonight that united plane is back in service, but the Flight Attendant has been removed from her duties as they investigate. Miguel almaguer, nbc news.
