Outspoken actor and comedian Denis Leary has hit out at US President George W Bush and his allies, insisting he condemns every policy he has made in office.

The RESCUE ME star would love the opportunity to correct Bush's catalogue of mistakes - starting with an administration overhaul.

He says, "The first thing I would do is fire (Vice President) Dick Cheney, or scare the s**t out of him so that he had a massive heart attack.

"Basically I'd do the exact opposite of everything that Bush has done.

"I don't understand him or his administration."
