Washington — With the House poised to vote to impeach the president as soon as Wednesday, lawmakers have already begun looking ahead to a potential Senate trial in January.

The House Judiciary Committee submitted a report to the House Rules Committee summarizing the articles of impeachment and the investigation into the president’s dealings with Ukraine early Sunday morning. The 685-page report is a supplement to the two articles of impeachment the Judiciary Committee approved on Friday: abuse of power and obstruction of Congress.

The Rules Committee will meet Tuesday morning to determine the length of floor debate over the articles, setting up a vote for Wednesday. Senators have already begun looking ahead to a trial in the upper chamber, with Senate Minority Leader Chuck Schumer writing a letter to Majority Leader MItch McConnell Sunday night demanding several witnesses be called.
