John O. Brennan was one of President Obama's most trusted national security advisors during all eight years of the Obama Administration, first as assistant to the president for homeland security and counterterrorism and then as director of the Central Intelligence Agency. Mr. Brennan had previously worked in the CIA from 1980 to 2005, where he specialized in Middle Eastern affairs and counterterrorism and served as President Clinton's daily intelligence briefer. Mr. Brennan received a bachelor's degree in political science from Fordham University in 1977 and a master's degree in government from the University of Texas at Austin in 1980.
"""John Brennan is one of the hardest-working, most patriotic public servants I've ever seen, and our country is better off for it. As president, he was one of my closest advisors and a great friend. And in his memoir, Undaunted, you'll see why. I hope you'll read it."" --President Barack Obama ""Brennan's memoir presents a rich portrait of his unusual life, which took him from a working-class New Jersey neighborhood to a position as a Middle East specialist who met with kings and presidents and witnessed the rise of Al Qaeda...[His] reflections on his long and momentous career are a worthy addition to the available history of the post-9/11 era."" --The New York Times (Editors' Choice) ""It's a full Brennan, from beginning to end. This is a headstrong and unapologetic book, one whose author tells us what he really thinks."" --The Washington Post ""Former CIA director Brennan gives a fly-on-the-wall view of life in Langley"" --Kirkus Reviews"
