The Biden administration is threatening to take back more than $170 million in COVID aid from Arizona over anti-mask rules, reports The Washington Post.

The Treasury Department in a letter to Republican Gov. Doug Ducey's Office of Strategic Planning and Budgeting said the state has 60 days to either make changes to two federally subsidized state school programs or redirect the money toward "eligible uses."

The funds are intended "to mitigate the fiscal effects stemming from the COVID-19 public health emergency, including by supporting efforts to stop the spread of the virus," the Treasury Department noted in the letter.
