This is CBSI on the world.

I'm John Bachelor.

I welcome my colleague of many decades, Craig Unger,

his new book, Den of Spies, Reagan, Carter, and the secret history of the treason that stole the White House.

This is October's surprise, put together, finally, after decades. Craig, congratulations. Good evening. We go immediately to the tragedy inside the tragedy. It is April 24, 1980, at a spot in the Iranian desert called

Desert One. There are Americans on the ground, including a rescue team.

And the mission is vouchsafed by the President of the United States, Jimmy Carter, and his

administration, waiting in the White House for word of the rescue efforts, these men will carry out.

Who are they aiming to rescue?

And what happens that day?

Good evening, to you, Craig.
