Legislators on Capitol Hill took aim at the government’s drone program on February 7, stepping up demands for more information from the White House on the legal justification for targeted killings of terrorists.

After years of secrecy about the program that has caused the deaths of American terror suspects and civilians, President Barack Obama called top senators on the Senate Select Committee on Intelligence late Wednesday evening and agreed to turn over the Justice Department’s full legal analysis of the program. The move came days after a DOJ "white paper" was leaked to NBC News and the night before the confirmation hearing for John Brennan, the nominee for Central Intelligence Agency director who is regarded as a main architect of the drone program.
