New Jersey Governor Chris Christie knew about the closures of local lanes leading to a busy bridge to New York City while they were happening, a lawyer for a former ally has said.

David Wildstein said he had evidence to show Mr Christie knew about the lane closures, which caused a huge traffic jam at the George Washington Bridge.

On Friday, Mr Christie was pictured leaving a birthday party for radio host Howard Stern. He has reiterated he had "no prior knowledge" of the closures.
