Sen. Chris Van Hollen of Maryland has announced he will challenge New York’s Chuck Schumer for the job of Senate majority leader, pushing the party into a fresh debate over its future just days after sweeping victories in the midterm elections.

Van Hollen made the announcement on Thursday, saying voters sent a clear message in the midterms — that they want “change from the status quo.”

“It’s now on us to meet this moment, and to do that we need new leadership,” Van Hollen said in a statement. “This is not about any one person — it’s about answering the call of the American people. That is why I’m running for Senate Majority Leader.”
