Transcript for Mitch McConnell is facing scrutiny from Democrats on impeachment vote
Now to Washington and the historic full house impeachment vote looming next week. President trump tossed the coin at the start of the army-navy game in Pennsylvania. Wednesday impeachment vote Wednesday on the house floor. With senate majority leader Mitch Mcconnell facing criticism from Democrats accusing him of taking his cues from the white house. ABC's David Wright with the latest tonight from the white house. Reporter: Tonight, the battle lines over impeachment are sharp and hyperpartisan. I am trying to give a pretty clear signal I've made up my mind. I'm not trying to pretend to be a fair juror here. Reporter: Speaking in Doha, Qatar, senator Lindsey graham said trump will be on safer ground with a Republican majority calling the shots. And I will do everything I can to make it die quickly. Reporter: On Fox News, senate majority leader Mitch Mcconnell vowed senate Republicans will be in lockstep with the white house. We'll be working through this process hopefully in a fairly short period of time in total coordination with the white house counsel's office. Reporter: President trump has said he'd like to call witnesses, but now says he'll defer to the senate. I'll do long or short. I have heard Mitch, I have heard Lindsey. I think they are very much in agreement on some concept. I will do whatever they want to do, it doesn't matter. Reporter: Democrats accuse senate Republicans of pre-judging the evidence even before the trial begins. And, when the house votes this week, Democrats from trump-friendly districts are under pressure to break ranks. 31 Democrats are seeking re-election in districts trump won, two of them have already said they're likely to vote no on one or both articles of impeachment. One may be switching parties. Other moderates are weighing their decisions. I'm going to read everything. Watch all the testimony and the hearings and read the transcripts, consult with scholars. And of course talk with my constituents. Reporter: Today, New Jersey congressman Tom Malinowski got some boos when he told residents in his district he plans to vote for impeachment. I believe that on the two counts of impeachment that had been put before us that the vote should be yes and I will be voting yes. All right, some applause and boos there. David Wright joins us live from the white house. The house is planning that historic vote this week. Expected to pass even with those moderate Democrats under so much political pressure. Reporter: That's right, Tom, the vote likely to take place Wednesday and the math in both chambers adds up. The Democrats in the house believe that they have more than enough votes to impeach president trump. Republicans in the senate believe they have the votes to keep him in office. As you know, Tom, the constitution requires a two-thirds vote to remove a David, thank you. Programming note tomorrow on "This week," George sits down with house judiciary chairman Jerry Nadler, Adam Schiff and senator Ted Cruz of Texas.
