WASHINGTON, DC - U.S. Senator Markwayne Mullin (R-OK) joined U.S. Senators Ted Cruz (R-TX), Bill Hagerty (R-TN), U.S. Representative Andy Biggs (R-AZ), and several of their Republican House and Senate colleagues in sending a letter to Attorney General Merrick Garland raising their concerns about the Department of Justice's failure to address non-citizens registered to vote in American elections. This letter comes after Attorney General Garland ignored a prior request for information as state officials revealed more examples of non-citizens being registered to vote.
