Watch Jon Lieber, who leads Eurasia Group's coverage of political and policy developments in Washington, lend perspective to this week's historic impeachment proceedings.

Impeachment. President Trump became the first president ever to be impeached twice this week. And the question on everybody's mind is will he be convicted in the Senate? And I think the answer right now is we just don't know. I'd probably bet against it. There was a really strong Republican vote against impeaching him in the House, with only 10 of the over 100 Republicans breaking with the President and voting to impeach him. And the question now is in the Senate, is there more support for a conviction? Senate Majority Leader McConnell has indicated he's at least open to it and wants to hear some of the facts. And I expect you're going to hear a lot of other Republicans make the same statement, at least until the trial begins.
