EX-CIA Director John Brennan: How I rose through the ranks and ran top-secret missions for multiple presidents

John Brennan is the former director of the CIA, a position he held until this past January. Now he’s attempting to retire for the second time. In April, Brennan was invited to speak at The Masters golf tournament in Augusta by Intersport for a summit on leadership. Business Insider’s US Editor in chief, Alyson Shontell interviewed him there about everything from how he joined the agency to president Trump, to what it was like in the situation room when Osama Bin Laden was killed. We've turned that interview into a special episode of “Success How I Did It.”
