Sen. Bernie Sanders announced Tuesday that he will not support Sen. Chuck Schumer's bid to remain the top Senate Democrat following the party's midterm victories that gave Democrats control of Congress.

The independent from Vermont, who caucuses with Democrats, made the remarks at a Capitol Hill press conference alongside Sen. Elissa Slotkin of Michigan. Sanders praised Schumer personally but called for new leadership.

"I personally have known Chuck Schumer for over 30 years, and I like Chuck. Nobody works harder than Chuck Schumer," Sanders said. "But in my view, the time is now for change, and I will not be supporting Chuck to be re-elected as the Democratic leader."

Sanders tied his stance to the election results, arguing that voters demanded a shift in direction on economic issues including income inequality. He suggested the leadership contest could spark a public debate on the party's future.

Slotkin echoed the call for change without endorsing a specific candidate. She said she would withhold support until seeing a concrete plan for the new majority's priorities.

Schumer, who has led Senate Democrats since 2017, expressed confidence in retaining the position ahead of the December leadership vote. He said the caucus remains united on key goals.

Neither Sanders nor Slotkin is seeking the role. Both highlighted Sen. Chris Van Hollen of Maryland as a potential challenger. Van Hollen has indicated he is considering a bid.

The announcement highlights divisions within the Democratic caucus despite its strong midterm performance. Senate Democrats will elect their leader next month, requiring a majority of the caucus for the position.
