A sold-out crowd Thursday, to hear one of the most prominent experts on national security and intelligence, in America.

General Michael Hayden was in town for the Jefferson Educational Society's Global Summit X.

General Hayden certainly has an extensive knowledge of America's security and intelligence, and he says America is living in a post-truth world, where politics and debate is about appeals to emotion, not facts.

General Hayden has had a 40 year military career, a Four-Star General in the United States Air Force, now retired, he's also the former Director of the National Security Agency, Deputy Director of National Intelligence, and was CIA Director for three years.

And now, an author. He wrote the book “The Assault on Intelligence: American National Security in the Age of Lies.” A harsh subtitle but one which Hayden believes to be true, “I don't think that he (President Trump) instinctively uses objective reality as the departure point for many of the things he says and does, it's instinct, it's intuition it's confidence in some a pirori narrative in how the world works,” said Hayden.

The book, and his lecture on Thursday at the Jefferson Educational Society, was about the negative effect President Trump is having on the intelligence community.

During a one-on-one interview with Erie News Now, Hayden says while those in the intelligence community are doing their best, they're having a hard time adjusting to President Trump's character and personality, “We've got to go in there and somehow get our storyline, our narrative into the head of a president who instinctively, is frankly, I'm going to be very candid, is broadly uninformed about international affairs, and for the most part incurious about those things, now that makes our job even more difficult,” said Hayden.

General Hayden tells Erie News Now that Trump's words and tones are different than any of his 44 predecessors, which is having an impact on national dialogue, “The tone in America was not created by President Trump, but President Trump is not doing much to heal that tone, and in fact in many instances he tries to exploit and worsen that tone,” Hayden said.
