Republican Ben Carson has started a petition calling on the IRS to target the nation's largest Muslim advocacy group.
The retired neurosurgeon accused the Council on American-Islamic Relations on Thursday of violating its nonprofit tax status in a Facebook message. Carson said the organization "brazenly violated IRS rules" when it called last month for him to leave the 2016 presidential race.
"Under the Obama administration, the IRS has systematically targeted conservative nonprofit groups for politically motivated audits and harassment," Carson wrote. "The agency should now properly do its job and punish the real violators of America's laws and regulations."
