The Senate voted March, 7, 2013, by a vote of 63 to 34 to confirm John Brennan, President Barack Obama’s nominee to head the Central Intelligence Agency after a filibuster sparked by the administration’s policy of targeted killings of terrorists.
A day earlier, Republican Sen. Rand Paul staged a 12-hour filibuster to draw attention to his demand that Obama explicitly say whether he thinks he has the constitutional authority to order the killing of noncombatant American citizens on U.S. soil. - NBC News
