5:35 p.m.

The former Navy SEAL who says he killed Osama bin Laden is denying a drunken driving charge filed against him in Montana.

Authorities say O'Neill was charged after officers found him asleep early Friday in a running vehicle and he refused a test to determine his blood alcohol level.

O'Neill released a statement through a public relations firm late Friday afternoon that says he took a prescribed sleep aid to help him with severe insomnia.

The statement says he is innocent of the charge and is pleading not guilty.

He also thanked police for their professionalism and courtesy.

Montana authorities have filed drunken driving charges against the former Navy SEAL who says he fired the shots that killed Osama bin Laden.

Butte-Silver Bow County Undersheriff George Skuletich says officers found Robert O'Neill asleep early Friday in a running car parked at a convenience store in his hometown of Butte.

Skuletich says the 39-year-old O'Neill was confused and appeared to be intoxicated when officers woke him up.

The officers took him to jail after he failed a field sobriety test. They charged him when he refused a breathalyzer test. He was released after posting a $685 bond.

A phone number listed for O'Neill was disconnected. It's not clear whether he had hired an attorney.

O'Neill began publicly discussing his role in the 2011 bin Laden raid two years ago.
