Pinal County, Arizona Sheriff Paul Babeu on Tuesday won the Republican primary in Arizona's 1st Congressional District.

The race to become the GOP nominee included six Republicans, although Arizona House Speaker David Gowan dropped out. Others in the race included former Secretary of State Ken Bennett, retired Air Force pilot Wendy Rogers, rancher Gary Kiehne and businessman Shawn Redd.

“A big thank you to the Republican voters who have decided that they want to send a sheriff to Washington,” Babeu said in his victory speech to supporters.

Babeu's campaign has largely focused on immigration and protecting coal jobs.

“I'm focused on talking about our national security, securing our border, protecting coal as an energy source and fighting for our state,” he said before prior to Tuesday's vote.

Babeu's previous attempt in 2012 to reach the House imploded amid allegations that he threatened to deport a former boyfriend if he discussed their relationship. Jose Orozco's undocumented status, which he claimed Babeu was aware of, ran contrary to Babeu's get-tough stance on illegal immigration. Babeu instead sought re-election as sheriff and was later exonerated of any criminal charges.
