Transcript for Democrats make final impeachment plea in the Senate
This is a first never before has this country faced a presidential election with a sitting president mired in impeachment. Today house managers and president's attorneys finished their closing arguments in the senate trial. President trumps acquittal is all but certain given the Senate's vote last week. To not allow witnesses but as Mary Bruce reports tonight we're hearing from Republicans who say while the president's conduct was not in. Teachable. It was wrong. Heading towards defeated Democrats on the senate floor today with a final pleased Paul is not lost. Even at this late hour. The senate can still. Do the right thing. Urging Republicans to consider the lens of history chairman Adam Schiff with a pointed warning. You can't trust this president to do the right thing not for one minute not full won election not for the sake of our country. You just can't. He will not change. And you know it but the president's lawyers argued the decision should be up to the American people the answer is elections. Not impeachment they insist the president effort to pressure Ukraine to investigate Joseph Biden was completely appropriate. The president has done nothing wrong but a growing number of Republican senators disagree even as they prepared to acquit the president. Things it's not something they should've been done and I think that. Needlessly inviting a lot of controversy. When you're going after a person may not even be her bone. They say the president's actions while not impeachable were not right as pal is something that I wouldn't have done I think he shouldn't have done and think it was wrong. And Mary Bruce joins us now live on Capitol Hill and Mary even though the trial is winding down it sounds like this investigation into what happened as far as this aid to Ukraine. That may not be over. Get on the house does still have some options your House Speaker Nancy Pelosi has not closed the door yet on the possibility that they could issue a subpoena the former national security advisor John Bolton but it's not the thing that seems intact that seems very likely at this point they haven't been talking about a lot of course have been wanting to wait and see what happens over in the senate but it is still a card that they could potentially play limbs and give us a sense of what you know at least of the president's plans for tomorrow and if he made the tackle impeachment during his State of the Union Address. It certainly is going to be elephant in the room look the White House says that the president plans to deliver a positive message and Republicans that I talk to here on the hill are urging the president to avoid the issue of impeachment entirely but with the president set to be a quit the very next day the big question is whether he can resist. Touting some kind of victory Lindsay Mary crews all over our impeachment coverage we appreciate you.
