As a part of the $1.9 trillion pandemic help bundle that Congress handed earlier this yr, states and cities had been awarded $350 billion of relief money that they may use for all kinds of functions.

The Treasury Division is giving Mr. Ducey 30 days to vary or finish the packages, in any other case the federal funds invested in them could possibly be clawed again.

“We’re involved that two not too long ago created Arizona grant packages undermine evidence-based efforts to cease the unfold of Covid-19,” Mr. Adeyemo mentioned.

A spokesman for Arizona’s lawyer normal didn’t instantly have a remark.

The Biden administration has given states broad discretion over how they will use the restoration funds; nonetheless, there are some restrictions.

Arizona is certainly one of a number of Republican-led states which have sued Treasury over a rule that prevents states from using the relief money to subsidize tax cuts.

The letter to Mr. Ducey was the primary warning that the Treasury Division has despatched to a state over what it views as misuse of funds.

States across the nation have been locked in authorized battles over masks mandates or bans in opposition to masks necessities in faculties.

A superior court judge struck down Arizona’s ban on faculty masks mandates final month. The state’s Supreme Court docket agreed final week to listen to the case, leaving the standing of the legislation in limbo till later this yr.
