Operation Garden Plot

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.
