Calls for Chuck Schumer (D-NY) to resign as Senate minority leader are growing louder by the day following his cave to Republicans on a government funding bill.

In a scorching letter first shared with POLITICO, a coalition of progressive youth groups accused Schumer of betraying their generation and lacking the spine to stand up to President Donald Trump’s agenda.

“Chuck Schumer, your leadership is failing to meet the moment,” the letter states. “Gen Z voters want leaders with a backbone who will stand up to billionaires and fight for working people. But it’s not just us. You have lost the trust of millions of voters and many of your colleagues in Congress.”

Signed by the Sunrise Movement, College Democrats of America, United We Dream Action and Voters of Tomorrow, they warn that Democrats “will cede even more young and working-class voters” if the party doesn’t change course.

“If you want our support, it’s time to get bolder, get louder, or make way for leadership who will. If you don’t get this right, we are ready to take the reins of this party ourselves to shape it into a force that can fight for working people and defeat growing authoritarian power.”

Meanwhile, the rebellion against Schumer has now spread to Capitol Hill. Rep. Glenn Ivey became the first House Democrat on Tuesday to publicly call for Schumer’s ouster as minority leader. Similarly, when asked during a town hall meeting if Schumer should resign, Rep. Delia Ramirez (D-Ill.) didn’t hesitate with a resounding “Yes.”

Desperate to justify his support for the GOP funding bill, Schumer claimed on MSNBC that he was making a strategic choice.

“The Republicans weren’t going to negotiate with us! So there were two choices only,” he explained. “It would be nice if we had a third choice. But in the Senate the only two choices were these choices. If you don’t have a shutdown, you can go to court, and we’ve had some successful results in the courts.”

Despite the growing dissent, Schumer’s position appears secure for now, as he won’t face reelection until 2028 and few in the party believe he will be replaced beforehand.
