Lets walk you through some of whats going to happen. Two attorneys general saying they are planning to sue President Trump and accuse him of violating anticorruption clauses in the constitution. That lawsuit reportedly set to focus on alleged payments to trump businesses from foreign governments. All eyes on a Senate Intelligence committee tomorrow. Attorney general Jeff Sessions, who recused himself from russiarelated investigations, has agreed to testify. Hell face tough questions about his contacts with russian officials and his dealings with fired fbi director james comey. And on wednesday, the president celebrates his 71st birthday. In an email, the first lady urged supporters to sign a special birthday card that her husband will never forget. And on friday, the president plans to outline policies with cuba. Hes expected to roll back some of the changes made by the Obama White House that opened commerce and travel between the two nations after a halfcentury. We have a lot to cover this week. Lets start at the white house. Nbc national correspondent, Peter Alexander is with us. Good morning. Reporter good morning. That new lawsuit, to be announced today, accuses the president of violating the constitution by accepting gifts from foreign governments without the okay from congress. The latest move by democrat attorneys general to challenge the president and his policies. This morning, the president is facing new legal trouble. This time, not related to russia. The Washington Post reporting that the attorneys general of washington, d. C. And maryland, two democrats, are slated to announce a major lawsuit against the president as early as this afternoon. Alleging that he violated anticorruption clauses in the constitution, by accepting millions in payments and benefits from foreign governments since moving into the white house. Essentially breaking his promise to keep his private business interests separate from his public role as president. It comes as President Trump spent the weekend away from the white house, at one of the properties in new jersey, seen here crashing a wedding reception saturday night. On sunday, back on twitter, attacking fired fbi director james comey as a leaker, with this swipe totally illegal. Very cowardly. That outburst targeting comey, after he testified last thursday that he would see what the fbi could do when the president asked him to back off Michael Flynn. It was kind of a slightly cowardly way of trying to avoid telling him were not going to do that. Reporter this morning, the president is facing mounting pressure, some from his own party. Youre your own worst enemy, mr. President. Knock it out. You may be the first president in history to go down because you cant stop inappropriately talking about an investigation that if you were just quiet would clear you. Reporter Top Democrats pouncing on the president s willingness to testify under oath. 100 . He said he would testify. So im inviting him to come testify. And we can work that out. Reporter while mr. Trump denies telling comey to drop the fin investigation, his own son appeared to confirm comeys version of the events. When he tells you to do something, theres no ambiguity in it. Theres no hey, im hoping. You and i are friends, i hope this happens. But you have to do your job. Thats what he told comey. Reporter while the president s allies are insisting they should close the book on the russia investigation, in fact, its only heating up. Attorney general Jeff Sessions expected in the hot seat tomorrow, agreeing to appear before the Senate Intelligence committee. This morning, its still unclear whether that testimony by Jeff Sessions will take place in public or behind closed doors. Sessions recused himself from overseeing the russiarelated investigations, when he admitted to having two meetings with the Russian Ambassador during the trump campaign. Investigators right now are trying to nail down whether there may have been a third undisclosed meeting. Sessions aides strongly deny that happened. Were joined by Nicolle Wallace and nbcs steve corn yaek. Good morning, guys. Good morning. Nicole, ill start with you. Sessions testimony is interesting, well get to that in a minute. The president himself raised the specter of testifying. He was asked whether he would testify under oath about the incidents james comey testified. That is a good idea . Its not a good idea if you love him or hate him, he has a very loose relationship with the truth. He trotted out birtherism for many, many years. And he came back and said never mind. He had his aides go out and argue a dem straebl demonstrably false fact about the number of people at his inauguration. Its one thing in a political theater, where his supporters say hes blowing up a convention. Its another thing entirely in a court of law where you lie or Say Something one time and Say Something different another, its called perjury. Steve, one of nicolles old colleagues in the white house, ari fleisher, said effectively over the weekend to donald trump, stop talking. Youre walking into a, quote, giant perjury trap. How much could these comments, these tweets, these public statements come back to haunt him . Yeah, no, what hes saying, what nicole is saying is true. If he Presses Forward with this, if he ends up under oath, says something that could be contradicted later on, it could be a perjury situation. I think one thing we have to keep in mind is this is ultimately still a political question. Think of the last president impeached, bill clinton. There was no dispute from his supporters and offenders it was perjury. Did the perjury rise to an impeachable level. And it was a political dispute. Democrats said no. Republicans said no. Republicans could impeach him, couldnt remove him. I think that same dynamic would stick here. Lets talk about the attorney general. Its reported that he will be testifying in some fashion before the Senate Intelligence committee. What is at stake here . Why is it important for him to get out there and clear the air . The public versus private is key. You can understand why sessions wants this in private. You already know hes going to face withering questions from democrats about those two meetings he failed to disclose. Now, we have word potentially in the private session last week, comey said there was a third meeting. Were getting denials from sessions people. That would be a point of emphasis. If he denies it or theres nothing there, he has explaining to do as it is. I want to ask you about tapes. Are there tapes . Are there not tapes . The president with a cryptic statement a couple of days ago. Director comey said i hope there are tapes. If theres tapes, we probably would have seen them. He loves the tease. The tv man loves the tease. If there were tapes, we would have seen them teased up. I think if there are tapes it would more likely corroborate what comeys version of the events are than trumps. Comey is a prosecutor who took notes for the purpose of remembering his own Actual Experience in an investigation or interrogation. I think the fact were talking about, yeah, hes likely to perjure himself but it wont lead to impeachment suggestion that week after week the bar keeps moving. It keeps getting lower and lower for this white house. Maybe hell perjure himself but he wont get impeached over it. Its an extraordinary time. Something tells me well see you again this week, guys. Thanks again. Also breaking at the white house overnight, President Trumps wife, Melania Trump and son, barron, now officially have made the move to 1600 pennsylvania avenue.
