We want to move to the latest on the sexual misconduct allegations that are rocking the the senate race in Alabama. This weekend, faith leaders gathering in Birmingham to condemn the rublican candidate, Roy Moore. David Wright is covering the story from the white house this morning. David, good morning to you. Reporter: Good morning, Dan and Paula. The outcome of this open senate seat smack in the moifld the bible belt matters to the white house. It comes at a time when institutions across the country are grappling with the abuse of the pate ree arky. One liberal pastor is calling this a battle for the soul of the nation. In Alabama, plenty of religious conservativeses still have faith in judge Roy Moore. Even after at least eight women have accused him of inappropriate including allegations of sexual assault. Most say they were teenagers at the time. Moore vehemently denies he's guilty of any such thing. They're not only untrue, but they have no evidence to support them. Reporter: A growing number of liberal preachers are calling the candidate out. More than 50 pass tors have signed a letter declaring him unfit for office. What is happening right now in Alabama matters for the soul of the nation. Just like the March cross the Pettis bridge mattered. Reporter: On Saturday, the former head of the north Carolina naacp, addressed an anti-moore rally in Birmingham. He's been empowered by folks like Steve Bannon, and white supremacists. Reporter: The campaign is collecting more donations reportedly since the scandal broke than in the six weeks since he won the primary. The white house is very interested in the race. They're keeping close tabs on it through intermediaries. Steve Bannon, the president's former chief strat jest gist is one of Roy Moore's biggest supporters. In that race, the election just around the corner. The 12th of December. One more question. We learned that the president said don Jr. Had an encounter with a Russian banker in may at an NRA dinner. What can you tell us? Reporter: We can confirm the meeting fook place. They had a brief conversation at the dinner. Went back to their separate tables. Why this matters is that investigators are trying to piece together what contact high-level trump associates may have had with Russians during the campaign. This banker is someone that has been reported to be one of the people trying to set up a direct meeting between Putin and trump. The Kushner camp chalking it up to small talk, nothing else. David Wright, thank you. Let's bring in George Stephanopoulos, who hosts "This week" later this morning. Good morning. Good morning, guys. Let's talk about Roy Moore. The front page of "The Birmingham news" says stand for decency, reject Roy Moore. It goes on to endorse the democratic rival. There's quite a lot of pressure. Could he still put out a win? Well, Alabama is still a very Republican state. There's still a chance. Roy Moore's core supporters stand in defiance of the establishment. You're seeing the establishment speak out against Roy Moore there. You have the major newspapers. The Republican leadership in the senate right now saying, they can't work with Roy Moore. The president is a bit of a question mark. He has said that Roy Moore should step aside if if allegations are true. He and the white house have not come down one way or the other on if the allegations are true. Seven different women have come forward now. Even the attorney general says the allegations are credible. The president hasn't yet take an stand. The latest polling, one poll shows Doug Jones, the Democrat, does have a lead. But I thing that's just one piece of the evidence. The election is still 3, 3 1/2 weeks away. Anything can happen there. They seem to be getting a record number of donations since the scandal broke. The Republicans desperately working for the first win of the year. They passed the tax bill in the house. They have passed the baton to the senate. You have Susan Collins on the show today. They can only lose two senators. Senator Collins says she has a lot of problems with the bill. She doesn't like that they have included the repeal of the Obamacare mandate in the bill. She doesn't like the estate tax. This could cause medicare cuts in the future. Will that be enough for her to say no to the bill? That's one of the questions I'm going to ask her. She's not the only one with real questions out there right now. You have senator John McCain. Senator Bob corker both concerned about the process and the deficit. Another senator, Ron Johnson, says he doesn't like the tax cuts for small businesses, how they're structured. You lose three senators, the bill doesn't go anywhere. Up a kl of problems for the bill. As it stands is that it's tremendously unpopular. This would be the most unpopular tax bill ever put before the congress right now. A huge problem. Number two would be, in their attempt to try to keep the deficit numbers down, they have made the corporate tax cuts permanent but the individual tax cuts temporary. That's drawing the fire of people like senator Collins as well. Weighed against that, Republicans need a win. Nay need a win going in to the midterms. There's a lot of pressure for the entire party to hold together. Really high stakes here for everybody. Thank you, George. Thanks, George. I want to remind everybody, George has a big show this morning. He'll speak with Republican senator Suzanne Collins. He'll have more on the debate over sexual harassment now rocking Washington.
