(April 2008) In the spring of 2007, a retired senior official in the U.S. Justice Department sat before Congress and told a story so odd and ominous, it could have sprung from the pages of a pulp political thriller. It was about a principled bureaucrat struggling to protect his country from a highly classified program with sinister implications.

Rife with high drama, it included a car chase through the streets of Washington, D.C., and a tense meeting at the White House, where the president’s henchmen made the bureaucrat so nervous that he demanded a neutral witness be present.

The bureaucrat was James Comey, John Ashcroft’s second-in-command at the Department of Justice during Bush’s first term.
