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.”

Van Hollen, 67, was elected to the Senate in 2016 after spending more than a decade in the House representing a Maryland suburb outside of Washington, D.C. One of his party’s more progressive members, he gained national attention last year lobbying for the release of Kilmar Abrego Garcia after he was wrongfully deported to a prison in El Salvador.

His announcement comes at a moment when progressive activists, as well as some Democratic lawmakers, are calling for Schumer, 75, to be replaced as party leader. Schumer has served in the role since 2017, but drew the ire of many inside the Democratic base for not taking a tougher stance against President Trump during a fight over government funding in early 2025.

“I welcome any discussion about the future of our caucus and the important work ahead. I’m proud of what we’ve accomplished together—55 seats and counting is an amazing result—and I have the votes to continue serving as Democratic Leader,” Schumer wrote on social media following Van Hollen’s announcement. “I look forward to leading our new Democratic majority and delivering for the American people.”

While Schumer has maintained he has the votes to become majority leader, he has faced growing resistance from inside the Democratic caucus. Earlier this week, Sen. Bernie Sanders, the Vermont Independent who aligns with Democrats, said he would oppose Schumer. He made the announcement next to Michigan Democrat Elissa Slotkin, who did not say outright she would oppose Schumer, but told reporters, “I am seeking change.”
