Sater provided such valuable information to U.S. intelligence agencies - such as five of Osama bin Laden's satellite phone numbers (by flipping Mullah Omar's personal secretary, "who was living inside a cave with bin Laden") - that the FBI and two federal prosecutors showed up at his trial after the $40 million stock scheme caught up with Sater - and vouched for him.

Felix Sater, provided valuable and sensitive information to the government during the course of his cooperation, which began in or about December 1998. For more than 10 years, he worked with prosecutors providing information crucial to national security and the conviction of over 20 individuals, including those responsible for committing massive financial fraud and members of La Cosa Nostra.

To this day, Sater continues to cooperate with the FBI and Justice Department, he said in his statement to the House Intelligence Committee. He wouldn't disclose additional details, except to say that he works on “international matters.” Two US officials confirmed Sater continues to be a reliable asset.
