US Marshal Accused of Being Mob Mole Appears in Court

A U.S. marshal accused of leaking information about a key mob trial witness says he felt he'd been "thrown into a vat of quicksand" when he realized he faced possible criminal charges.

A sometimes tearful John Ambrose testified Tuesday at a hearing to determine whether statements he made before being formally charged will be admissible in court.

Ambrose says he was intimidated into making the 2006 statements to prosecutors.

Defense attorneys say Ambrose was effectively under arrest and should've been read his rights. Since he wasn't, they say his statements shouldn't be admissible. But prosecutors say Ambrose wasn't under arrest and made the statements freely.

Attorneys gave no indication what Ambrose told prosecutors.
