Republicans will have almost the same razor-thin majority in the House when the new Congress is sworn in on Jan. 3, but the composition will look quite different in many ways. Due to flipped seats and a wave of retirements, there will be more than 60 new House lawmakers walking the halls of Congress come next year.

House Republicans will have a narrow majority in the 119th Congress, at 220 to 215, with that majority further slimmed at least temporarily to 217-215 after Trump tapped a few members to join his administration. In the Senate, 12 new members will be sworn in as Democrats prepare to give up control to the Republicans, four of whom are Republicans who flipped blue seats.
