Biden and his potential vice president will formally accept the party's nomination at the
Democratic National Convention, scheduled for Aug. 17-20, and he is expected to announce his pick before it begins.
The
New York Times reported earlier on Monday that Biden's campaign plans to announce a decision as soon as Tuesday, but more likely on Wednesday, citing people briefed on the selection process.
It noted that Biden has missed previous deadlines to announce his pick, and that the timeline could "slip again."
