Trial Under Way for Deputy Marshal John Ambrose Accused of Leaking Secrets to Mob

The trial is under way for a deputy U.S. marshal accused of leaking the secrets of an FBI investigation to the mob.

Prosecutors said in court Monday that 42-year-old deputy marshal John T. Ambrose deliberately helped the mob, while Ambrose's defense attorney claims he merely said too much while boasting to a friend.

Ambrose is accused of leaking the contents of a secret file on the star witness in the government's landmark Operation Family Secrets mob investigation.

Assistant U.S. Attorney T. Markus Funk told jurors the case is about, "a criminal betrayal of trust." Defense attorney Francis Lipuma told them Ambrose merely went too far while talking about his job with a former police officer who was like a father to him.
