Jon Lieber, who leads Eurasia Group's coverage of political and policy developments in Washington, shares his perspective as Congress considers a second impeachment:

Big story this week is the president of the United States is about to be the only president ever to be impeached twice by the House of Representatives. Articles of impeachment should pass the House on Wednesday morning. The difference between this impeachment and the last impeachment is that this time there will be Republican support for the removal from office. A Senate trial can't begin until probably after the president has left office however. So this really isn't about kicking him out. It's about holding him accountable for the riot that happened at the Capitol last week, and potentially disqualifying him from ever running for future federal office. All eyes will be on the Senate and while it doesn't look likely that he will be convicted there, should some of the more prominent leaders in the Senate come out in favor of his impeachment, I think you may find the 17 votes you need in order to convict Trump.
