Leading members of the House Armed Services Committee emerged from a classified briefing on the Edward Snowden leaks Wednesday afternoon “shocked” at the amount of information he reportedly leaked beyond the NSA surveillance programs.

Rep. Mac Thornberry (R-Texas), chairman of the Armed Service panel’s Intelligence, Emerging Threats and Capabilities Subcommittee and also a member of the House Intelligence Committee, said the briefing on the defense consequences of Snowden’s leaks was “very highly classified,” and therefore details couldn’t be discussed.

Thornberry did say that lawmakers “left the briefing disturbed and angered” after hearing that the leaks by the former Booz Allen Hamilton employee “went well beyond programs associated with the NSA and data collection.”
