The Maryland Democrat has been critical of Schumer, who has led the caucus for nearly a decade.

Sen. Chris Van Hollen announced Thursday that he would challenge Chuck Schumer for the top Democratic leadership role in the Senate, arguing the party needs to take a more populist direction.

“In this election, the American people called for change. They called for a change from Donald Trump’s disastrous policies — but even bigger than that, a change from the status quo that isn’t working for working people,” Van Hollen, who represents Maryland, said in a statement obtained by The Washington Sun.
