He's also a member of the conservative Republican Study Committee. "Franks said in a 2011 interview that "[gay marriage] literally is a threat to the nation's survival". He served a term in the state House in the 1980s.
His Arizona district went big for President Trump in the presidential election, and he was considered a reliable supporter of the president's agenda.
The AP reported on Franks' resignation Thursday afternoon, based on its sources.
