An Osama Bin Laden associate named Hassan Ghul, who was captured in 2004 and spent two years in a CIA prison, was killed in a drone strike after NSA signals intelligence pinpointed his location. The Washington Post reports that the documents provide an account of NSA-CIA collaboration in the drone campaign. A secret NSA unit called Counter-Terrorism Mission Aligned Cell, or CT MAC, spent a year tracking Ghul before he was killed.
A report in the Washington Post reveals that the NSA collects hundreds of millions of contact lists, approximately 250 million per year. An internal NSA presentation said that an estimate of 500,000 buddy lists on live-chat services and inbox displays of email accounts were gathered per day.
