Sen. Ted Cruz (R-TX) slammed the Biden administration on Thursday for its vaccine mandates, despite his own support for vaccines, noting that the mandates pose a threats to people’s jobs which in some cases pose a risk to U.S. national security.

Cruz’s remarks come after the U.S. Court of Appeals for the Fifth Circuit halted Democrat President Joe Biden’s mandate last month, citing potential “grave statutory and constitutional issues with the Mandate.”

“The Biden White House mandates have been struck down repeatedly by the courts,” Cruz told reporters on Thursday.
