The Pentagon needs to explain who was responsible for providing sensitive information about Jordan’s role in training moderate Syrians to fight the Islamic State, two key Senate Armed Services Committee members said Wednesday.

Sen. John McCain, R-Ariz., and Sen. Lindsey Graham, R-S.C., said they are pushing to find out who made the decision to reveal Jordan’s role in establishing one of four sites to train and equip up to 1,200 vetted Syrians and then return them to fight against the Islamic State.
