The Republican Debbie Lesko, a former State Senator, and the Democrat Hiral Tipirneni, a doctor, won primary elections in Arizona’s Eighth District on Tuesday, according to The Associated Press.

They will face off in the general election on April 24 to fill the congressional seat, which is considered safely Republican. The seat was vacated by Trent Franks, a Republican, after he was accused of offering an aide $5 million to be a surrogate mother.
