Kentucky Attorney General Daniel Cameron joined 20 other state attorneys general in calling on the U.S. Treasury Department to make sure the most recent COVID-19 relief package cannot undermine states’ tax policies.

The attorneys general sent a letter to Treasury Secretary Janet Yellen earlier this week raising concerns about portions of the $1.9 trillion American Rescue Plan Act. The officials state sections of the law preclude states from using federal funds from the bill to offset a reduction in tax revenues.
