A group of moderate House Democrats had negotiated for a vote by Monday, arguing that they should claim victory on infrastructure before the more contentious package of $3.5 trillion of social programs is resolved.
House Speaker Nancy Pelosi, D-Calif., announced the infrastructure vote is slipping to Thursday, when the federal highway program expires.
One of the leaders of the moderate faction, Rep. Josh Gottheimer, D-N.J., insisted Friday that the infrastructure bill will be approved.
But Rep. Pramila Jayapal, D-Wash., said dozens of members of the Progressive Caucus will oppose the bill on its own and could reject it unless the $3.5 trillion is approved, too.
