In a hearing called to assess current and future national security threats, some of the most prominent members of the US intelligence committee were grilled on how to handle the ongoing leaks from Edward Snowden and criticism of its surveillance efforts. This mornings remarkably hostile Senate hearing pitted Director of National Intelligence James Clapper, FBI head James Comey, and their Congressional supporters against senators who wanted hard, public answers to questions whose answers have been kept ambiguous or under wraps to all but a few officials. In a series of curt questions, Senator Ron Wyden (D-OR), a longtime surveillance critic, extracted hard promises of information from the NSA, CIA, and FBI.
