"President Biden would veto a Republican resolution to nix the vaccine-or-test mandate for businesses with 100 or more employees if it made it to his desk, the White House said on Tuesday. Republican senators are poised to force a vote this week to nix the Occupational Safety and Health Administration’s rule after they failed to block funding for the mandate last week in the government funding bill. White House press secretary Jen Psaki said the White House is hopeful that the Senate will push back on the “anti-vaccine and -testing crowd” and confirmed Biden's intention to veto the resolution.

Democratic Senators Joe Manchin (WV) and Jon Tester (MT) have said they would back a vote against the mandate, a challenge that is supported by all 50 Republican senators. The support from Manchin and Tester gives Senate Republicans enough votes to pass the resolution, but it would still need to pass the Democratic-controlled House before making it to Biden’s desk. Democrats in the House are not expected to bring the measure to the floor, but GOP supporters could use a discharge petition to try to force a vote. That would involve winning the support for the measure from a majority of House members."
