In recent weeks, two dozen state attorneys general have threatened Biden with litigation over his proposed COVID vaccine mandate, referencing the order’s constitutionality.

According to a 7-page letter, the states agree the proposed vaccine mandate would lead to essential healthcare workers quitting or losing their jobs as the country remains in a pandemic. The letter was in response to Biden’s mandate for every employer in the US with 100 employees or more to require proof of vaccination or face weekly testing.

Biden’s response to reporters inquiring about the potential litigation was for them to “have at it.”

State Attorneys General signing the letter include Alabama, Alaska, Arizona, Arkansas, Florida, Georgia, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Montana, Nebraska, New Hampshire, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Texas, Utah, West Virginia, and Wyoming.
