After almost 19 years as House Democratic leader, Speaker Nancy Pelosi of California is expected to step down at the close of this Congress, ending a historic career that included trying to end George W. Bush's Iraq War, implementing President Barack Obama's signature health-care law, impeaching President Donald Trump twice and squeezing President Joe Biden's sweeping agenda through a narrowly controlled House.

Rep. Hakeem Jeffries of New York is the early favorite to become the next Democratic leader, but the maneuvering for power has just begun, and fights over who else should be on the leadership team could pit the ideological factions of the caucus against each other.
