US marshal accused of leaking secrets to mob

April 12, 2009 (CHICAGO) Chicago Deputy Marshal John Ambrose is accused of giving the mob inside information about a witness in the 'Family Secrets' trial.

It was one of the most important mafia trials in years. The witness was hit man Nick Calabrese, who was crucial to the convictions of several mafia leaders.

In secretly recorded conversations at a federal prison, two mob leaders talked about a man they called "The Babysitter," who was allegedly leaking information. Authorities say that man is Ambrose.

He denies the charges.
