Transcript for Trump weighs in on impeachment trial
And president trump, meantime, was on the world stage, 4,000 miles away, but fully aware of what was playing out right here in Washington. At the world economic forum in Switzerland, he celebrated the strong U.S. Economy, but he had choice words for the impeachment trial, too. Here's ABC's chief white house correspondent Jonathan Karl tonight. Reporter: The message from president trump at world economic forum in Davos, Switzerland, even as the impeachment trial gets under way in Washington, he's hard at work on the world stage. We're meeting with the biggest companies in the world, the biggest businesses in the world and world leaders, all for the benefit of the united States. Reporter: One leader not on the president's schedule, Ukrainian president volodymyr zelensky, who is also at Davos. But president trump told "The Wall Street journal" that he would be willing to meet with zelensky, adding, quote, he's a really good guy. The president's only comments on the senate trial, brief and familiar. That whole thing is a hoax. It goes nowhere because nothing happened. The only thing we've done is a great job. So I'm sure it's going to work out fine. Jon Karl with us live tonight across town at the white house. And Jon, you've learned tonight that president trump has been briefed on the proceedings so far? Reporter: And aides here said he almost certainly watched some of the proceedings. The bottom line for the white house is, this was a first test of whether or not Republicans in the senate would remain united and now, towards the end of this first day, not a single Republican defection on any of those procedural questions and for the white house, David, that's a win. That's what the president wants. Jon Karl live at the white house. Jon, our thanks to you. Mary Bruce, our entire team in Washington. Our coverage of the impeachment trial for tonight.
