president trump's turn in his impeachment trial, after listening to the democrats make their case three days after why the president should be removed from office, his legal team will get their first chance today. they'll start to respond to the two articles that define the president's impeachment abuse of power and obstruction of congress. they're expected to resist democrats call for witnesses and other documents. what are we expecting to hear from the president's team today? >> good morning, everybody. the president's team will give america a sneak peek of the case before, quote, getting into the nitty gritty on monday, they'll argue that the president did nothing wrong, that this is all a political act. and they'll attack joe and hunter biden to make the point that president trump was justified in calling to investigate them. the they follow house democrats who made a passionate plea for witnesses and documents to preserve they say what this country stands for. >> give america a fair trial. give america a fair trial. she's worth it. >> with that, house democrats closed their case against president trump late last night as they seek to remove him from office. today, the president's legal team will begin laying out his fans led by pat cipollone and the president's personal attorney, jay sekulow. >> we're going to refute what they've put on and make a case as well. >> this has been a painful period. >> president trump's team is brushing off a new videotape, where the president appears to say get rid of then ambassador yovanovitch a full year before she was removed. >> get rid of her. get her out of there. take her out, okay? do it. >> abc report this is recording captures some of the president's party guests, including former white house aide, john destefano and two now indicted affiliates of rudy giuliani, but the president denies knowing lev parnas. >> he's a con man. i don't know him. >> >> i want ambassadors that are chosen by me. i have a right to hire

why. >> i was shocked, absolutely shocked, and devastated, frankly. >> reporter: democrats are seeking to include more evidence and testimony from key witnesses during the trial. and a new reuters poll suggests seven in ten americans agree, they also want to hear from witnesses who were blocked from testifying by the white house during house proceedings. president trump argued about the timing of his team's opening arguments as, quote, tv's death valley. with no public events on his schedule and whether it is too rainy for golf, guys, i think it's fair to say that the president himself will be upping those ratings. jeff? >> the latest numbers say otherwise, but thank you very much. >> congratulations, guys. >> thank you very much. kevin cirilli, chief correspondent for bloomberg news. lay out what's going to happen today. >> this morning is the first opportunity for the president's legal team to make their case after they had the 24-hour marathon by the impeachment prosecutors and democrats to make their case. the president is not happy about this, simply because of the timing. they would like to see some prime time action. that's what i'm hearing from my sources. ultimately they're going to save a little bit of the action for early next week to really make some of their case. >> how does this new audio recording factor in? >> it is factoring in, in the sense that we were talking a little bit about this before i got on air. it matters to the public. the expectation, it's been baked in that senate republicans will not vote to impeach or to convict president trump, but to the public, the republicans now need to answer to that, to this new type of evidence. >> it's almost like there's two trials. >> yeah. >> the one going on in the senate and then the court of public opinion. at least in mentioning that recording, will we see new witnesses and will we see new evidence coming forward, any indication? >> i'm struck by the notion that this conversation over witnesses is still being had by sources connected to senate majority leader mitch mcconnell. they would like to see this trial move efficiently and over the next week and a half. that said, republican sources tell me why weren't -- why wasn't all of this decided in the house side? now democrats are push iing, making a transparency argument. either way, when you take a step back here, february 4th, mark your calendar, the president's state of the union address. that's the working timetable of when the president wants this done. >> does that come down to lamar alexander? you have collins, murkowski and romney all open to witnesses. does that then all come down to lamar alexander? >> yes. point blank. in a word. >> in essence, i would also suggest open to witnesses is not saying there has to be witnesses. so there's this washington wiggle room that candidally we're all used to. >> there was this notion by the democrats that rudy -- that president trump was influenced by rudy giuliani, who is there for some kind of, i guess, lackey, so to speak, of president putin in russia. that has floated to the surface here in a way that i could frankly had not heard before. >> i spent the week traveling with secretary of state mike pompeo through latin america, but i asked him in an interview point blank about this notion that democrats have raised that there's a shadow foreign policy or shadow state department and he is adamant there is not. >> jeff mention this had idea if they could get enough republicans we could possibly see the witnesses. what right now will be the strongest argument that they've made? >> their argument is what took so long and why are we here? you had all of these months of investigations in the house and ultimately they feel that it's their job now to decide whether or not to convict. that said, the polling suggests, especially in battleground states, that voters, independent voters especially want to see lawmakers taking this trial seriously. >> vote against the president and your head will be on a pike, a cbs report, seems to be playing a role right now, especially as we heard things wrapping up for the democrats. >> precisely. when adam sc hichlt ff, chairman of the house intelligence committee, read that in the last 24 hours on the floor, during that, there were audible gasps and eye rolls to some extent and republican senators saying that they were not told that. however, again -- and it's excellent reporting -- speaks to the notion of the public trial you and i were just talking about. they want to see lawmakers on both sides taking this seriously. >> yes or no, will it have any difference? will it make any difference? >> which? >> on the overall situation, the vote. the vote. >> look, i would be -- based upon my reporting and who i talk to, i know i'm not saying yes or no, but my reporting, i would be surprised if ultimately this trial drags out. >> you're being honest. >> we rarely get the yes or no answer. >> i'm trying. >> it doesn't matter what i think. it matters what they think. >> there it is. >> thank you. >> senate impeachment trial of president trump picks up again this morning. we'll bring you the

klobuchar are running for president. >> some things are more important than politics. i took an oath to up hold the constitution. we're in the third impeachment trial of the united states. of course i am here. >> it is disappointing to me not to be in iowa, talking to the people there. >> don't you think it's important business? >> here? of course it is. i'm accepting my constitutional responsibility. >> in their absence, the senators have sent friends and family out on the road. new york congresswoman alexandria ocasio-cortez campaigned for sanders in iowa. >> it's not that we

public remains low. >> just do general healthy measures. that's what you should be doing right now. >> reporter: the major concern here is this virus comes from the same family as other dangerous illnesses such as sars and the bird flu. a study published in the medical journal "the lancet," suggested that a person infected with coronavirus may be able to spread it even if they're not showing
