President. And 2020 shakeup. Bernie sanders is in. Joining the growing democratic 2020 field. But will he be able to pull the same support this time that he had in 2016 . An awful lot to get to, but we start with the breaking news. A new investigation into one of President Trumps first supporters on the campaign trail and First Advisors in the white house, michael flynn. The House Oversight committee will investigate his role in a plan to transfer Nuclear Technology to saudi arabia. Something that may have broken laws. But investigators fear trump may still be considering it. Flynn has already pleaded guilty to lying to the fbi about his conversations with the Russian Ambassador during the trump transition. He has met with Robert Muellers team 19 times. National security reporter ken delaney is here with these late breaking details, what can you tell us . Reporter whistle blowers from within president Trumps NationalSecurity Council have described fears about the plan to transfer Nuclear Technology to saudi arabia. Theyre saying that mike flynn had a conflict of interest because he had been advising the group. Theyre saying that flynn and others tried to push this plan through and get an order for trump to sign without the required review thats necessary whenever the United States transfers Nuclear Technology to a third country. This was a project that was backed by jack keane, who had been considered by President Trump as secretary of defense. One top official is quoted as saying, this is a scheme for these generals to make money. You know we cannot do this. So career officials are trying to stop this, but the plan went forward anyway. And the report by the House Oversight committee out this hour says that Derrick Harvey was pushing this plan and even presented a draft order for the president to sign that would have been tom berrick a special env envoy. House investigators are saying theyre concerned about, this plan appears to remain on the table, even though mike flynn is long gone and work has seized in the National Security council in this project. They worry President Trump is still considering transferring Nuclear Technology to saudi arabia and theyre concerned that could lead to saudi arabia producing a nuclear weapon, chris. Thank you for this breaking report. I want to bring in matt miller, kimberly adkins, and john meachum, all three msnbc contributors. Matt, so the Oversight Committee reportedly said its investigation of the plan is particularly critical because the administrations efforts to transfer sensitive u. S. Technology to saudi arabia appear to be ongoing. What do you say to the fact that congressional investigators think the administration is still pursuing this deal . There are two things that struck me about kens report. This potentially illegal, if it were to have been executed in the way it was originally planned, managed to hang around the administration for so long. It lasted long past mike flynns resignation and according to the committee maybe even is still alive in some form or fashion today. Thats the first thing. The second thing it reminds me of even if you take away the russia investigation, and everything that bob mueller has found, all the people who have been indicted in that investigation, all the people that have pled guilty, all of the other corruption scandals that surround this president and all the other potential things the House Oversight committee has to probe. There are four cabinet officials who have already had to resign in scandal, a number who are still in scandal and you have other threats like this for them to pull when you look at the way that the Trump Administration has been influenced by foreign powers. And the key thing that struck me in this report is that the House Committee has whistleblowers inside the National Security council. If i were working in the white house and i knew that people inside ingovernmethe government closest to the white house you can get were talking to congression congression congression congressional committees i would be concerned. You can predict what the pushback would be. In other words, this is this administration has perfected its ability to try to discredit every investigation thats touching the Trump Administration and the trump world more broadly. So i think well certainly see that and well probably hear a lot about the deep state because of the whistleblowers that matt was talking about. I think one thing that is striking about this new investigation is that its yet another thread between the Trump Administration and saudi arabia. Weve seen with, for example, the reaction, the very slow reaction to condemn the murder of the Washington Post reporter. The question is why . Is it because President Trump is reluctant to criticize saudi leaders because of his personal business ties . Is it Something Else . Now here is yet another bit of evidence of something going on between the u. S. And saudi arabia. So as these investigations go on we see more dots being created. As i was reading through kens report, we got it a few moments before we went on air. This is the latest in a long line of examples where either not knowing or willfully ignoring what has kept this institution, this democracy going for all these many years, is that there are safeguards in place. And it does seem like that there is if this is so, another instance where those safeguards were not just even thought about. You know, the difference between journalism and history is its an iceberg. History is what you can see below the surface once time passes. Whats interesting is investigations bridge that gap, if you will. They enable us to see more than we can see in a daytoday basis. The National Security council was created in the late 1940s to manage the possibility of manage preventing armageddon, that was the point. It was a cold war institution. Weve seen historically because its an executive arm more so than state department and the pentagon, it can lead president s to great moments of diplomatic breakthroughs, as the end of the cold war under president george h. W. Bush. Or it can lead to freelancing and trouble, which it led under president reagan and iran contra. This feels like the latter than the former. Then you have roger stone, just three days after the judge imposed a limited gag order on him, he posted an instagram picture of the judge with what appeared to be crosshairs of a gun site. He deletes the post and puts it back up without the crosshairs. Then his lawyers enter a court filing apologizing to the court for the improper photograph and comment posted on instagram today. Mr. Stone recognizes the impropriety and had it removed. Just in the last 30 minutes, judge jackson scheduled a hearing for thursday afternoon to discuss why the Media Contact order entered in this case or his conditions of release should not be modified or revoked in light of the posts on his instagram account. What in the world is going on with roger stone . First of all, we ought to say about this post he made yesterday how despicable it really was. There are federal judges who have been assassinateded for their work. Its something the u. S. Marshals takes very seriously. Im sure theyre doing a threat assessment now and trying to decide whether they have to increase security on judge jackson either because all of the attention in this case or at the very least implied threat roger stone made on instagram yesterday. Whats happening now is exactly what roger stones attorneys must have feared when they got him to take down the post and issue the apology to the judge yesterday. She has two things she can do, one is to tighten or revoke his bail and two is to extend the gag order. Right now its a loose gag order from him. Hes free to talk to the press in other form or fashion in any way he wants. What she could do is extend the gag order and give a gag order like the one she imposed in the manafort case that prevents him from talking about the case at all. Clearly his attorneys were worried about this and thats whey they made him apologize yesterday and take the post down. Ive just got handed a statement, jeff bennett, who is one of our white house reporters was in touch with roger stone. He said in a text i will be present for the hearing as ordered, but did not engage when asked by nbc news about his motivations for posting the Instagram Photo in question. And whether hes worried about judge Amy Berman Jackson revoking his release. Your thoughts . Social media has a great deal to offer the world and great deal to take away from it. One of the interesting things about this whole era is going to be to what extent did the culture around President Trump, candidate trump and then President Trump, to what extent was it shaped by technology, to what extent did it shape it . The fact you have someone in this kind of legal jeopardy whos posting Instagram Photos is remarkablremarkable. We would tell our children not to do anything remotely like this. Commonsense i think has to i agree with matt. This is a serious thing. We forget sometimes that it just takes one unstable person to react to a climate of suggestions of violence and extremity of the paranoid style in american politics. We saw it with the mail bombs last year. And history gets changed for the worse by people who are part of a climate and react to a climate of violence. We just need to the president should denounce it. We need to stop doing it. In the meantime, kimberly, youve got the ongoing revelations from andrew mccabe. Today Savannah Guthrie asked mccabe if he had briefed leaders of the socalled gang of eight. That he had opened this counterintelligence investigation into President Trump. Heres what he said. The purpose of the briefing with was to let our congression congression congression congression congressional leadership know what weve been doing. This is a recommendation that chy came to me. I discussed it at length did you Tell Congress . I told congress what we had done. Did anyone object . Thats the important part. No one objected. Not on legal grounds, not on constitutional grounds and not based on the facts. No objections from congressional leaders. Whats your take away . There will be a lot of questions will be asked of the leaders about what they knew about this. And when they knew it. Its a remarkable revelation thats made by andrew mccabe. Hes talking about it now. Its yet again, another dot in this picture thats being painted of the Trump Administration and its reaction to and relationship with federal prosecutors and investigators. Its extraordinary. John, im being told my time is up, but i have to ask you, the president has been punching back about the mccabe interviews. Among the flurry of tweets, plotting a coup and treason. What is your thought about throwing around words of coup and treason . Its part of the sulfurous nature of the era. Treason is a technical definition. Which i dont think the president probably knows. The only thing defined in the constitution quite specifically. Words matter. The tone matters. And Franklin Roosevelt once said the presidency is not primarily an Administrative Office or an engineering office. Its chiefly a place of moral leadership. You help shape the dispositions of heart and minds of the country. The disposition is being shaped for the ill. Busy day, thanks to all of you. Appreciate it. Up next, selling point . The president is using an Emergency Declaration to build the wall. Were sure to hear about it in his campaign rallies. Senator Bernie Sanders is now in.

And it is as complicated as it is consequential. Here are the basics. 16 states have filed suit to block the president from spending billions on a wall, arguing congress controls spending. Heres the key section of the lawsuit. Contrary to the will of congress, the president has used the pretext of a manufactured crisis of unlawful immigration to declare a National Emergency and redirect federal dollars appropriated for military construction and Law Enforcement initiatives towards building a wall on the United States. Its worth noting that brandnew poll shows the president is losing in the court of Public Opinion with 61 of voters saying they do not approve of the president s National Emergency. But, of course, the real court fight is just beginning. The Colorado Attorney general, thanks for being with us. I want to make sure people understand this. The lawsuit says the states are going to court to protect their residents, their Natural Resources and their economic interests. So help us understand, for example, in colorado, give us an example of how you argue this is harmful. We have a number of military bases, installations here, take fort carson for example. They have lots of people working there. They have lots of physical imkbrumi improvements. Those are going to be at risk if you move money to build a border wall. That will hurt colorado. The president is pushing back this morning. As i predicted, 16 states led mostly by open border democrats and the radical left have filed a lawsuit in the ninth circuit. He loves to go after the ninth circuit. California, the state that has wasted billions of dollars on their out of control fast train with no hope of completion seems in charge. Open border democrats and the radical left. How do you respond to the president s tweet . I respond by saying this is about the rule of law and preserving our constitutional democracy. In politics, social media tweets can often be part of the game, but, frankly, in a court of law its about your legal filings. Its about the separation of powers, article i of our constitution is clear. Congress has the authority to appropriate funds. If we see a hijacking of our process, were undermined separation of powers. Thats what makes this case so consequential since the seizures case which involved president harry truman. Courts have long ceded to the president on issues of National Security. They are reluctant, as you know, to impose their own judgment about a security threat. So how would you argue against that . The steel seizures case is a good example. Harry truman said it was necessary to steal a steel mill. What was important in that case was congress had not authorized the act. Here, congress not only hasnt authorized the act, congress turned down the request. Thats what makes this case so important. When congress specifically turns down a request, if the president gets to say unilaterally im going to do it weve undermined separation of powers. That is very fabric of our sn constitutional design. Yours is one lawsuit. There are a lot of other ones. The defense secretary is reviewing what he can do, what programs he can cut to make this happen. How quickly could something happen here . Theres likely to be a preliminary injunction that will be round one. This is going to be a multipart effort. There will be appeals and ultimately this is very likely being decided by the u. S. Supreme court. Ive had the chance to work at the u. S. Supreme court for two justi justices. Both care deeply about separation of powers. Its a protection of liberty, its at the very fabric of our democracy. I believe the Supreme Court will side with us in this case. Thank you so much, appreciate it. Pleasure to be here. Bernies new battle. The vermont senator announcing his president ial campaign this morning.
