On his Twitter account, Steny Hoyer (D-MD) has confirmed that he will seek the Minority Whip post in the next Congress.

I am running for Democratic Whip in order to defend Dem accomplishments, unify our Caucus & begin the hard work of winning back the majority

That puts him in a tough race against James Clyburn (D-SC) — a black liberal with support from the crucial Congressional Black Caucus.
