WASHINGTON (AP): A former FBI explosives expert from Indiana will plead guilty to revealing secret information for an Associated Press story about a U.S. intelligence operation in Yemen in 2012. Donald Sachtleben of Carmel, Ind., says in court paper that he provided details of the operation to a reporter. Four months ago, Sachtleben also acknowledged he distributed and possessed pornographic images of underage girls. The plea agreement calls for 140 months in prison for both crimes.
