As Biden prepared for the high-stakes meeting with House Democrats on Thursday, Jayapal made an urgent plea on a call with White House chief of staff Ron Klain: Don’t send the president to pressure liberals to vote Thursday on the Senate’s infrastructure bill without a more progressive social spending bill that’s fully done.

Klain pushed Jayapal, who leads the Congressional Progressive Caucus, to vote for the infrastructure bill during the call, according to a source familiar with their conversation. Jayapal responded that she wanted to avoid sending Biden off to Europe on Thursday with a failed vote, according to multiple Democrats.

What happened next is a dizzying fall of dominos. Biden didn’t directly ask House Democrats to pass his bipartisan infrastructure bill, leaving Pelosi to make the request. Then Jayapal’s progressives dug in against the infrastructure vote that the speaker wanted to tee up — using the president’s lack of a request for cover.
