WASHINGTON (CNN) - Former Massachusetts Gov. Mitt Romney said Monday that he is giving Jay Garrity, the aide currently under investigation for impersonating a police officer, the "benefit of the doubt" until an investigation into the matter is concluded.

"I give him the benefit of the doubt. I hope other people do, too," Romney said Monday. "With regards to an investigation going on, of course we'll let that run its course."

"He's a good guy and I wish him the very best," Romney added. "But this is now in his hands. He's got his own counsel, and I am hoping things come out real well for him."

Garrity temporarily stepped down from the campaign on Friday after Police accused him of trying to impersonate a police officer on two separate occasions - once on the voicemail of a plumbing company, and a second time with a New York Times reporter in New Hampshire.

Garrity has denied the charges.
