WASHINGTON (WUSA) -- One book critic says he doesn't know how journalist Ron Kessler does it. Somehow he has convinced FBI agents to sing like canaries.

Kessler's book, "the Secrets of the FBI", is now out in paperbook.

Kessler is the same journalist who broke the story about the Secret Service's escapades in Cartagena.

On Wednesday's noon show, JC Hayward interviewed him about the book. Check out the interview in the video.
