As the House moves forward with its impeachment investigation against President Trump, many of the 2020 Democratic candidates are preparing to head back to Washington for the Senate trial. This reprieve will leave the campaign trail wide open for two candidates in particular: Joe Biden and Pete Buttigieg.

House Speaker Nancy Pelosi has suggested Democrats will hold a vote on the proceedings before the winter recess, which means a Senate trial could take place in the weeks leading up to the Feb. 3 Iowa caucuses and the Feb. 11 New Hampshire primary. Senate Majority Leader Mitch McConnell has said that if impeachment does go to trial, senators will need to convene “every day, six days out of seven.”
