Democratic Sen. Chris Van Hollen of Maryland said Thursday that he will run for Senate Majority Leader in the next Congress, setting up a challenge to Democratic Leader Chuck Schumer after the party swept to power in the midterm elections.

Van Hollen said in a statement that "the American people called for change" and that is why he is running.

"It's now on us to meet this moment, and to do that we need new leadership," Van Hollen said.
