Lawmakers summoned to spy briefing

The director of the National Security Agency will brief lawmakers on the agency's surveillance programs after the House nearly voted to curtail the agency’s powers.

NSA Director Gen. Keith Alexander will answer House members’ questions about the agency’s surveillance activities in a classified, members-only briefing. The briefing is to be held as lawmakers prepare to head back to their districts for the month-long August recess, where many expect to get questions from constituents about the NSA.
