Donald J. Trump becomes the first U.S. President to be impeached twice and is among only 2 others to be impeached at all. He was impeached for inciting the insurrection of the Capitol on January 6th, 2021, the day Congress certified the election results. The trial to convict Trump is expected to take place after the inauguration of Joe Biden. At that point, Mitch McConnell will no longer be the Senate Majority Leader, instead, Chuck Schumer will be. Mitch McConnell has stated that he is unsure if he will vote to convict. That alone is a huge deal. That could mean that Trump might actually be convicted in the Senate trial (if 17 Republicans vote to convict). To convict an impeached president, there must be a 2/3 vote (67 Senators) of the Senate to convict Trump.
10 Republicans voted to impeach Trump in the House. That is 10 more Republicans to vote for impeachment than his last impeachment.
