Panetta to CIA staff: Hey, maybe it's time to stop leaking about the OBL raid

In Panetta’s letter, obtained by CNN, he says the operation, “has led to an unprecedented amount of very sensitive — in fact, classified — information making its way into the press.”

“Disclosure of classified information to anyone not cleared for it — reporters, friends, colleagues in the private sector or other agencies, former agency officers — does tremendous damage to our work. At worst, leaks endanger lives,” the letter said.
