Earlier in the week. This morning, how bad its going to get and how long the big chill will last. Highspeed chase a Dramatic Police pursuit in houston, caught on camera. Two suspected bank robbers racing down the highway, slamming into cars, riding on their rims, with sparks flying. The police chase finally coming to an end, with this dramatic attempt to carjack another car. This morning, the tale of the tape. And survival of the fittest. Chanel and two producers put their lives on the line, taking part in a simulated plane crash into the water. The Lessons Learned and the bonds formed. Today, saturday, march 4th, 2017. Announcer from nbc news, this is today, live from studio 1a in rockefeller plaza. And welcome to today on another busy saturday morning, im craig melvin. And im chanel jones. Were waking up to more drama this morning. President trump moments ago sending out a flurry of tweets. A Shocking Development this morning, writing on twitter that former president obama had his wires tapped at trump tower before the election. Lets get to casey hon in west palm beach. Good morning. Chanel, craig, good morning. President trump already up here at his winter white house in maralago. Tweeting potentially explosive new allegations about the Obama Administration wiretapping at trump tower just before the election. He writes, terrible just found out that obama had my wires tapped in trump tower just before the victory. Nothing found and he says, this is mccarthyism. This is just emerging, we have reached out to former Obama Administration officials and are trying to find out exactly the latest and what has happened. But this is shaping up to be another busy weekend for the president. President trump touching down in florida for another working weekend. It is not rest at the southern white house, its all work. Making the short trip from his maralago estate to the swanky four season, meeting with wealthy republican donors. In public, trying to turn the tables on democrats, tweeting this picture of nancy pelosi meeting with the Russian Ambassador after she claimed she hadnt. And in one of Chuck Schumer at a gas station with Vladimir Putin. For the record, schumer tweeted, they were krispy kreme donuts. The democrats arguing their meetings were out in the open while President Trumps associates meetings were secret. The latest former trump former policy adviser carter page who once said he had never met with the Russian Ambassador. This week did you meet Sergey Kislyak in cleveland durks talk to him . Im not going to deny i talked to him. Pressure is mounting, with democrats demanding that the Justice Department give congress more information about any investigation into Trump Campaign contacts with the russians. I would say at this point we know less than a fraction of what the fbi knows. Democratic senator chris kunitz telling nbcs Andrea Mitchell that there might be transcripts that the fbi isnt showing congress. There are transcripts that provide critical insight into whether or not russian intelligence and senior russian political leaders, including Vladimir Putin were cooperating, were colluding with the Trump Campaign at the highest levels, to influence the outcome of our election. Meanwhile, Vice President mike pence facing his own controversy. The indy star reporting he just turned over 13 boxes of emails, sent from a private business, sent from a private account while he was governor of indiana. Theres no comparison whatsoever between Hillary Clintons practice of having a private server, mishandling classified information. Hillary clinton was on a flight with her one of her former top aides when a fellow passenger caught a picture of her reading the u. S. A. Today story about mike pences emails, a little irony there. But i want to also point out the president still tweeting in the middle of a series of these, as we were just in that spot, how low has president obama gone to tap my phones during the very sacred election process . He said this is nixon watergate. Bad or sick guy. So set up to be a pretty busy day with us trying to figure out exactly what he means by this series of tweets. Explosive allegations. All right, kasie, thank you. Our nbc news political analyst, former Senior Policy Adviser for senator rand pauls campaign. Heres another tweet that President Trump posted. I bet a good lawyer could make a case out of the fact that president obama was tapping my phones just prior to the election. We dismiss a lot of his tweets as silly or ridiculous. But this is a bold assertion. And it looks like this is going to be something that he continues to do throughout the day. Whats he thinking . I think that he clearly is upset over all of the talk about his administrations ties with russia. And hes trying to turn the conversation by labelling people who are questioning these administration ties with russia, and the administration contacts, into the nixon. He hastened the comparison to nixon. So now everyone is doing that to him. They are rex nisant of nixon. Hes trying to change the subject . Exactly, by trying to prosecute obama and questioning surveillance powers that went through the fisa court. So this is not new information. We no that the intercepts between members of the Trump Campaign and russian officials, that under our nsa wiretapping program, that those transcripts are available, that that meta data is available. This is not new information. But he is clearly trying to take the offensive this morning. Lets put this into context. Its been quite a week. It started out to me on a positive note. He had his joint address to congress. And then came this drip, drip, drip as you were talking about with these russian allegations. In fact take a look at this screen here. We talk about the fact that five advisers during the Trump Campaign had meetings with russian officials before the inauguration. You have Jeff Sessions, michael flynn, jared kushner, carter page, j. D. Gordon. Theres a lot of smoke here, but is there any fire . And where do you see all of this going . Well i like that comparison of a drip drip drip. Now the faucet is running full and its going and its not going to stop. Thats the problem with President Trump rejecting any kind of investigation. If they were just forthright, we have nothing to hide. We were talking to russian diplomat counterparts, this could go away, if that is in fact what happened. By looking like theyre covering up something. The fact that all of these advisers have changed their stories so many times, its just a cloud of suspicion that it really is going to dog his presidency for at least the first two years as the investigation continues. Lets talk about the gallup poll that came out yesterday. We are roughly 50 days into the Trump Administration. His disapproval numbers just north of 50 . They continue to be among the lowest of any president at this point in their administration in modern history. Numbers like that, what do they do to the administrations ability to advance their agenda . Well i actually think its been a little overblown right now about his low approval ratings, i think its so early and also in a lot of the polls you can see a significant portion of voters who might have voted for President Trump just to oppose Hillary Clinton and theyre satisfied with his policies. They may not like his personality and the way hes behaving but theyre hopeful about what his policies are going to be. If he could control his personality, such as maybe not going on a tweet storm about Sensitive NationalSecurity Issues that are plaguing his administration, perhaps he would be doing better in those approval ratings. Or accusing a former president of tapping his phones. Im sorry, going into conspiratorial territory that makes me wonder whats in President Trumps mind. Lets get to the brutally cold temperatures gripping the east coast this morning after our warm winter, its a rude awakening today. Indira is in for us. Its been pretty unbelievable, right. Thats the case. Winter is hardly behind us just yet. Heres proof of that. Just take a look at the video out of pennsylvania, more than 30 vehicles were involved in this massive pileup on friday in whiteout conditions. Three people airlifted to nearby hospitals, no reported deaths at this time. So yeah, its early march, we typically would be looking at very cold air as you can see the maps right now. All the cold air making its way in from canada. Whats not normal is what weve been feeling. Its been this huge flipflop, everyones words have been how weird is this. Look at the temperatures we saw just on wednesday in new york. 70 degrees, it was humid, people were in tshirts, it was sticky outside. Temperatures about 35 degrees above normal and look at the difference this morning. Well get your National Forecast in just a moment. Theres a small amount of relief being felt among the Jewish Community this morning. After an arrest was made in relation to a stripping of threats made against houses of worship. Nbcs morgan raffert is here with more. Juan thompsons arrest is the first in connection with a rash of threats made against Jewish Community centers in 36 states. Prosecutors paint a picture of a disturbed man and a scorned lover who went to Great Lengths to get back at his exgirlfriend. In some cases saying she planted the bombs. And others, using his own name. After months of bomb threats, leaving jewish communities on high alert this is something that puts everybody on edge. The fbi says 31yearold Juan Thompson of st. Louis, missouri, made at least heat of those threats, his arrest coming as a relief and sobering reminder of a threat that still lurks. Just because theres been an arrest today around our bomb threat does not mean that the threats have disappeared or will stop. According to the fbi, thompson was a copycat making those threats to get back at an exgirlfriend after they broke up last july. Through a series of emails and phone calls, Authorities Say thompson said his ex was behind the bomb threats against the jews. And that she placed bombs in dallas, san diego, and at the antidefamation leagues new york headquarters. The he allegedly also made threats under his own name at schools and museums in new york and detroit. But later claimed the ex had made them. To set him up. Thompson appeared in a st. Louis federal court friday afternoon charged with one count of cyberstalking. His mother, telling nbc he is a good man. But thompson has a colorful past. Seen here, working for an online news site called the intercept, which fired him last year for allegedly making up sources and quotes. Prosecutors also cite comments allegedly posted from his twitter account just last week. Saying know any good lawyers . Need to stop this nasty racist white girl i date who had sent a bomb threat in my name. Thompsons arrest comes as more than 100 bomb threats have been made against Jewish Organization ace cross 36 states since the beginning of the year. Prompting rallies of solidarity to support jewish communities. If someone wants to try to instill fear that we are people that stand up and inspire courage. Leaders who say hate should never be met with silence. Thompson did not enter a plea at his arraignment and is not suspected in most of the other threats, which are still under investigation. Meanwhile, states like new jersey have beefed up security around religious centers, hoping to protect vulnerable communities. Chanel, craig . Morgan, thank you.
