Hanna, considered a moderate, has bucked the GOP party line on several issues since taking office in 2011. He was one of the few Republicans in the House to vote against cutting off federal funding to Planned Parenthood.
In March, Hanna told a crowd that they should donate to Democrats if they were concerned about women’s rights.
“I think these are very precarious times for women, it seems. So many of your rights are under assault,” Hanna said. “I’ll tell you this: Contribute your money to people who speak out on your behalf, because the other side — my side — has a lot of it.”
