When al Qaeda terrorists attacked the World Trade Center and the Pentagon on September 11, 2001, Michael Morell was with President George W. Bush at an elementary school in Florida as the CIA's daily briefer. The events that unfolded on that fateful day are just some of the many national security disasters that Morell, the former acting director of the CIA, has been at the center of since 9/11. The veteran intelligence official has spent much of his 30-year career out of the public eye, but he's stepping out of the shadows to talk about his new book The Great War of Our Time: The CIA's Fight Against Terrorism — From al Qa'ida to ISIS.
