President Trump was elected, at least in part, on a promise to upend the way Washington and its bureaucracies work.

That gave pause to some in the nation's intelligence community, including retired Air Force General Michael Hayden, who, during the George W. Bush administration, served consecutively as director of the National Security Agency and the CIA.

In his new book, "The Assault on Intelligence: American National Security in an Age of Lies," he critiques the president's campaign tactics, his behavior, and his governing style, especially as it relates to the nation's secrets and its spies.

General Hayden, welcome back to the "NewsHour."
