President Joe Biden met with centrist Democratic Sens. Joe Manchin and Kyrsten Sinema as his legislative priorities of infrastructure and voter access could be defeated in their chamber.

Biden broached both issues with West Virginia’s Manchin before the Senate votes Tuesday on whether to debate voter access. Although Republicans are poised to block the move, the White House is pushing Manchin to support the doomed measure so Democrats can present a united front and hold a debate on the floor that they calculate could come back to haunt Republicans.
