Brennan served in the White House as Assistant to the President for Homeland Security between 2009 and 2013. Obama nominated Brennan as his next director of the CIA on January 7, 2013. The ACLU called for the Senate not to proceed with the appointment until they confirmed that "all of his conduct was within the law" at the CIA and White House. Brennan was approved by the Senate Intelligence Committee on March 5, 2013, to succeed David Petraeus as the Director of the CIA by a vote of 12 to 3.
