Scoop: Dem senators' Biden huddle called off

The big picture: Sen. Mark Warner (D-Va.) last week was reaching out to Democratic senators about meeting to discuss Biden's path forward, but that meeting was never scheduled, a person familiar with Warner's thinking told Axios.

• Details of the proposed meeting leaking out made it impossible for there to be a private conversation, the source said.
• Senate Democrats as a whole will meet Tuesday for a regularly scheduled caucus meeting.

Zoom out: Democratic senators are having ongoing conversations about whether Biden should remain at the top of the ticket amid concerns about his mental acuity, the source said.

• While some lawmakers like Sen. Bernie Sanders (I-Vt.) have stood behind the president, many Democratic senators have remained mum.
• Senators return to Washington on Monday after two weeks away, and it will be the first time they are together since Biden's debate disaster.

• A group of top House Democrats on Sunday said Biden should drop out of the race.

Between the lines: Senate Majority Leader Chuck Schumer (D-N.Y) has publicly stood behind Biden.

• But he was telling political allies that an early debate would give the party flexibility going forward, including finding a new candidate.
