US Marshall Tells US Attorney and FBI He F@#%ed Up

Friends of ours: Nick Calabrese
Friends of mine: John Ambrose

As soon as the high-ranking deputy U.S. marshal sat down with U.S. Attorney Patrick Fitzgerald and FBI Chicago chief Robert Grant, he knew he was in trouble, federal documents allege.

"I fucked up," John Ambrose reportedly told both officials as they questioned him about whether he leaked sensitive information.

Ambrose, a member of the regional fugitive task force who also did a brief stint in witness protection, is charged with passing government material about protected mob witness Nick Calabrese to a third party. That information made its way to the mob, federal authorities contend.

Calabrese is a major government witness in the upcoming Operation Family Secrets mob trial. Ambrose was stripped of his duties last year and charged in January.

The allegations were taken so seriously that Grant and Fitzgerald took the rare move of sitting down with Ambrose last September. Prosecutors say they told him he faced criminal charges and risked losing his job -- but they contend they also told him he wasn't under arrest. If he were in custody, a Miranda warning would have been required. Federal prosecutors say Ambrose never asked for a lawyer and was free to leave whenever he pleased. "Mr Ambrose at times appeared anxious while reviewing some of the evidence against him," Grant said in a court affidavit filed Tuesday. "Mr. Ambrose on a number of occasions shook his head and repeated that he had fucked up."

Their contentions come in response to a filing last month in which Ambrose claimed that he was pressured into giving incriminating statements. "The pressure was so extreme that my body was shaking and my mind was racing," Ambrose said in court papers.

Ambrose's filing says he believed he was in custody. He is trying to get his statements tossed.
