Arizona Gov. Doug Ducey, a Republican, announced he will not provide funds to school districts that attempt to impose mask requirements for students in the state.

The governor said that district and charter schools in Arizona that follow state laws will be eligible for $163 million in grant funding that is intended to boost per-student spending.

But Ducey, in a statement, said that schools that impose mandates that go against state laws—including mask mandates—won’t receive the funding. According to the governor’s website, Arizona doesn’t mandate masks, vaccinations, or vaccine passports.
