Threats from moderates have infuriated progressive Democrats, who, emboldened by their successful effort to twist the Biden administration to introduce a new eviction moratorium, have repeatedly warned House Democratic leaders not to deviate from their original plan.

In a letter to Pelosi on Tuesday, the leaders of the Congressional Progressive Caucus said a poll of their 96 members confirmed a majority would withhold their support for the bipartisan infrastructure bill until the Senate passed the reconciliation bill.

White House officials have said that they remain closely attuned to the growing tensions in the House and Senate. Pelosi and Biden speak regularly, and aides have started holding thrice-weekly conference calls, according to sources familiar with the matter.

But top Democrats in Congress see no alternative to the path they are headed down and are hopeful that the two-track strategy will prove successful as in 2010. “I am very pleased to report that the two-track strategy is right on track,” Schumer said.
