Mitt Romney is parting ways with his Arizona campaign co-chairman after the politican faced allegations of misconduct.

Pima County Sheriff Paul Babeau stepped down Saturday after a man he'd had a previous relationship with accused Babeau of threatening to deport him if he talked about the nature of their interactions. Babeau is now acknowledging he is gay, but denied the allegations.

Romney campaign spokeswoman Andrea Saul said the campaign supports his decision.

The allegations against Babeau were first reported by the Phoneix New Times, an alternative weekly magazine.
