Arizona state officials certified Democratic Rep.-elect Adelita Grijalva’s special election win on Tuesday, with the state’s attorney general warning Speaker Mike Johnson (R-LA) that failure to swear in Grijalva or provide a “reasonable explanation” as to when the ceremony will occur will “prompt legal action.”

Attorney General Kris Mayes demanded Johnson swear in Grijalva “without further delay” in a letter sent on Tuesday and obtained by the Washington Examiner.
