House Democrats unanimously elected Rep. Joe Neguse (D-CO) to replace Rep. Jim Clyburn (D-SC) on Wednesday, the latest transition of power as longtime Democratic members look to pass on leadership responsibilities to rising members within the party.

Clyburn announced in February he would step down from his post as assistant Democratic leader without providing a reason, but he asserted he would be running for reelection in November. Neguse, who ran unopposed, will take on the assistant leadership role and forgo his position as chairman of the Democratic Policy and Communications Committee, the House Democrats’ messaging arm.
