Sen. Bernie Sanders announced Tuesday that he will not support Sen. Chuck Schumer for Democratic majority leader in the new Congress, signaling a significant challenge to Schumer's leadership. Sanders, an independent from Vermont, stated that the time is now for change and that he will not back Schumer's reelection as leader.

He was joined at a news conference by Sen. Elissa Slotkin of Michigan, who echoed the sentiment for a new generation of leadership and a thorough discussion of the Democratic Party's future priorities. Slotkin indicated she is not seeking the leadership role herself but wants to see potential leaders present comprehensive plans.

The call for new leadership comes after a strong midterm election performance by Democrats, who flipped several Republican-held Senate seats. Progressive factions within the party have reportedly been urging for a change in leadership.

Sen. Chris Van Hollen of Maryland is reportedly considering a run for the leadership position, though his level of support among colleagues remains unclear. Van Hollen stated he is currently engaged in conversations with his colleagues.

Schumer, 75, has expressed confidence in his re-election, stating his focus is on the upcoming year and "getting things done." While Senate Republicans met to choose their leaders, Senate Democrats have just begun their discussions ahead of leadership elections expected later this month.
