In 2020, during the COVID-19 pandemic in Arkansas, Hammer was one of several Republican state legislators who sued Arkansas GovernorAsa Hutchinson, a fellow Republican, over public health measures that he ordered to prevent the spread of the virus. An Arkansas judge dismissed the suit.[5]
In 2021, Hammer opposed the grant of a liquor-sales permit for a new Costco Wholesale in west Little Rock, a portion of which is in his district. Hammer wrote a letter to the director of the Alcohol Beverage Control Division, contending that the public's needs were "being adequately met by these existing businesses."[8] By contrast, Little Rock's mayor and vice mayor supported Costco's permit request.[8] The director initially denied Costco's permit application,[8][9] but this decision was reversed after a successful appeal by Costco to the Control Board directors.[9]
