2 top House Democrats won't say if Biden should run for re-election

Flashback: On Sunday, Sen. Joe Manchin (D-W.Va) would not commit to endorsing Biden for a second term, saying he was "not getting involved in that."

• Rep. Alexandria Ocasio-Cortez (D-N.Y.) also declined to endorse Biden for reelection saying "we'll cross that bridge when we get to it."

The big picture: The White House has said that Biden plans to run for re-election in 2024 despite a poll showing that a majority of Democrats would prefer a new candidate.

Yes, but: Some top Democrats still support Biden's bid for a second term, with Sen. Elizabeth Warren (D-Mass.) saying he "should be running" in 2024.

What they're saying: Nadler said during a debate for a Manhattan-area House seat that it "doesn't serve the purpose of the Democratic Party to deal with [Biden's reelection] until after the midterms."

• Maloney, his opponent, said that she doesn't "believe [Biden] is running for reelection.”
