Its been a whirlwind few days for the white house. President trump scoring victories in the passing of the gop tax plan by the senate and the overwhelming decision in favor of his travel ban by the Supreme Court. But along with that came serious legal concerns. Heres abcs david wright. Breaking news in the russia investigation. We begin with President Trump and his words for michael flynn. Michael flynn pleading guilty to lying to the fbi. Reporter today in washington, a news blizzard. Massive storms brewing on several fronts. The Trump White House the center of it all. In congress, a hotly contested tax bill on the verge of becoming law. Historic tax relief as a giant present for christmas. Reporter in alabama, a Pivotal Senate race rife with controversy down to the wire. Tonight the Supreme Court finally allowed the most recent incarnation of the president s longdelayed travel ban to take effect. And of course, overshadowing it all, theres the russia investigation. I think what were beginning to see is the putting together of a case of obstruction of justice. Reporter on any given night, any one of these stories could be leading the news, but in the trump era, its all coming at you at once. This latest news storm started friday with michael flynn. He pled guilty to lying to the fbi. Thats a felony. Now hes helping the special counsel. No, im not. Reporter the president insists he has nothing to fear. What has been shown is no collusion, no collusion. Theres been absolutely theres been absolutely no collusion. Reporter possible collusion may not be his only problem. On saturday morning this tweet from the president set off a firestorm because it seemed to suggest for the very first time that trump knew flynn had committed a crime when he fired flynn. Quote, i had to fire general flynn because he lied to the Vice President and the fbi. Thats potentially significant. Do you solemnly swear to tell the truth, the whole truth and nothing but the truth so help you god. Reporter because former fbi director james comey has given sworn testimony that trump asked him to go easy on flynn. I understood him to be saying that what he wanted me to do was drop any investigation connected to flynns account of his conversations with the russians. Reporter comey didnt back down. Trump ultimately fired him, too. Trump insists he never pressured comey to stop investigating him. The more the president knew about what flynn said to the fbi before he took action on comey, the more perilous it is for him. But there still remains an argument that youre going to need more than just he fired comey because of the flynn investigation. Reporter the white house scrambled to distance the president from that saturday tweet. Trumps lawyer insisted he drafted it for the president. Another white house official called it sloppy. The president also went on the attack, accusing comey of running the fbi into the ground, its reputation is in tatters, he tweeted, worst in history. He also questioned the integrity of the special counsels office after it came to light that Robert Mueller fired one of his top investigators in the russia probe last summer for sending what were potentially antitrump texts to a colleague during the campaign. This morning trump brought up clinton again, this time defending mike flynn. Hillary clinton lied many times to the fbi. Nothing happened to her. Flynn lied and theyve destroyed his life. I think its a shame. Reporter today the White House Legal Team floated an extreme option, testing out a controversial new theory that a president cannot obstruct justice because hes the chief Law Enforcement officer and, therefore, has a right to express his view on any case. I think what the trump team is trying to do here is conflate the question of can he be charged with obstruction of justice ever with could he be charged with obstruction of justice for firing james comey. Reporter he has control of personnel. He can make decisions for whatever reasons he wants. The problem for them is, i think if theres an obstruction charge here, its going to be based on a pattern of conduct. Its not just going to be based on firing james comey. Reporter all of this at the start of a week that has more bruising battles ahead. Early saturday morning the Senate Narrowly Passed tax reform, 5149. The tax cuts and jobs act as amended is passed. Reporter not one democrat voted in favor. Were talking about massive, massive tax cuts. Reporter the house has already passed its version of the plan. The president is hoping to have a version of the bill thats acceptable to both houses on his desk before christmas. This is a big legislative win, the most significant one for the Trump Administration thus far. And this is something to take home to your constituents. Reporter republicans insist the bill would pay for himself but the nonpartisan joint committee on taxation says the Senate Version would add 1 trillion to the deficit over the next decade. This bill is unpopular. Its being pushed by a very unpopular president and passed by a very unpopular congress. Thats not a recipe for political success. This is what it looked like. Reporter democrats are calling it a tax cut for the rich thats being pushed through without giving lawmakers time to read it. Here are the modifications in it. I can read one word, add this language. Can you tell me what that word is . Its about 500 hu hu00 pages reporter President Trump needs every vote he can get which is one reason today he gave Alabamas Roy Moore his full but seven women have accused moore of sexual misconduct, some of Sexual Assault when they were teenagers and he was in his 30s. Mr. Moore attacked me when i was a child. Reporter allegations moore denies. Today the president called moore from air force one and told him, go get em, roy. I think its a mistake. I think it tarnishes the republican brand and tarnishes the president to be associated with somebody that is an accused child molester. Reporter a new cbs poll finds nearly 3 out of 4 alabama republicans, 74 , dont believe the allegations against moore. The poll has moore ahead by six points among likely voters. The issue hits home for the president , too, for obvious reasons. You can do anything. Whatever you want. Grab them by the [ bleep ]. Reporter after the offcolor remarks from the access hollywo hollywood bus during the campaign, women came forward accusing trump of allegations. Allegations trump denied. Today billy bush, the former tb host who shared trumps joke on the bus published an oped in the new york times. The president initially excused his words on the bus as locker room talk. Thats locker room, thats locker roorm. Reporter more recently hes questioned the authenticity of the tapes. Bush disputes him saying, yes, donald trump, you said that. And that he believes the women who accuse trump of groping them. Steve bush is on steven colbe colberts show. Stop playing around with peoples lives. Reporter all of this and its monday. The weeks just getting started. In the trump era, we never know what headlines tomorrow night bring. Im david wright for nightline in new york. Next, even santa may not have as much Christmas Spirit as this couple. How they turned their Home Sweet Home into even sweeter fullsized gingerbread house. Afi sure had a lot on my mind. My 30year marriage. My 3month old business. Plus. What if this happened again . I was given warfarin in the hospital, but wondered, was this the best treatment for me . So i made a point to talk to my doctor. He told me about eliquis. Eliquis treats dvt and pe blood clots and reduces the risk of them happening again. Not only does eliquis treat dvt and pe blood clots. Eliquis also had significantly less major bleeding than the standard treatment. Eliquis had both. And that turned around my thinking. Dont stop eliquis unless your doctor tells you to. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. Eliquis treats dvt and pe blood clots. Plus had less major bleeding. Both made eliquis right for me. Ask your doctor if switching to eliquis is right for you.
