Brennan all over the place…Asia, Saudi Arabia… my God, while we slept all this was going on without an outcry from us. NO MORE.

Brennan's 25 years with the CIA included work as a Near East and South Asia analyst, as station chief in Saudi Arabia, and as director of the National Counterterrorism Center.[3][6][8]After leaving government service in 2005, Brennan became CEO of The Analysis Corporation, a security consulting business, and served as chairman of the Intelligence and National Security Alliance, an association of intelligence professionals.[9]

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.[10][11] The ACLUcalled 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.[12] 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.[13]

Cruz wouldn't say if CIA Director John Brennan should lose his job. "I think we should wait to discover what the facts are, but for the executive branch to spy on and hack into the computers of the United States Senate is an extraordinary violation of the respect that each constitutional branch owes the other, and so, if that is indeed what happen[ed], there should be serious consequences," he told the Washington Examiner outside the Senate chamber.

The fight between Feinstein and the CIA pertains to a Senate report on waterboarding during former President George W. Bush's time in office. McClatchy reported Friday that the CIA had learned of congressional staffers removing secret documents from agency headquarters by monitoring Senate computers.
