The US state of Florida on Thursday sued the Joe Biden administration over the COVID vaccine mandate the President announced for federal contractors. The lawsuit is set to become yet another battleground between Republican governor of the state Ron DeSantis and the White House.

The lawsuit was announced by DeSantis himself. It alleges that the president doesn’t have the authority to issue the rule and that it violates procurement law.

The lawsuit was filed in US District Court in Tampa and names Biden, NASA Administrator Bill Nelson as well as White House contracting officials as defendants, the Associated Press reported.

DeSantis has vowed legal action over federal vaccination requirements and fought masking and vaccine rules implemented by local governments in Florida. He recently announced he would call state lawmakers to the Capitol next month to pass legislation to combat vaccine mandates enacted by private businesses. With a possible 2024 presidential run in mind, DeSantis has been consistent in his criticism of Biden’s handling of the pandemic and other issues.

In addition to a vaccine mandate for federal contractors, which is set to go into effect in December, Biden has also announced that private employers with 100 or more workers will have to require them to be vaccinated or tested weekly. The roughly 17 million workers at health facilities that receive federal Medicare or Medicaid also will have to be fully vaccinated.

Biden has said that these vaccination mandates are the only way to end the COVID-19 pandemic that has claimed the lives of more than 740,000 Americans.

Republicans all over the country do not share Biden’s opinion and have opposed the vaccination requirements, threatening to bring similar legal challenges. 21 Republican state attorneys general sent a letter to the president on Wednesday saying that they think his vaccination mandate for federal contractors “stands on shaky legal ground,” is confusing to contractors, and could exacerbate supply-chain problems.
