The Senate passed a resolution Wednesday to repeal President Joe Biden’s vaccination-or-testing mandate for private sector employers in a bipartisan rebuke of a key component of the White House’s Covid-19 strategy.

The measure, which needed only a simple majority to advance, passed in a 52-48 vote.

It was supported by every Republican and two moderate Democrats: Sen. Jon Tester of Montana and Sen. Joe Manchin of West Virginia.

“I’m not crazy about mandates,” Tester told NBC News before the vote, later calling the federal requirements “burdensome regulations.”

The resolution was introduced by Sen. Mike Braun, R-Ind., who argued Biden had no authority to impose the requirements. Braun celebrated the Senate vote on Wednesday evening.

“This bipartisan vote is a crystal clear message to the @WhiteHouse: Back off, and stop this crazy federal overreach immediately,” he tweeted.

Senate Republicans argue that while they consider vaccines important, they believe the mandate is “unconstitutional.”
