Comey's recent testimony reveals that he and Ashcroft were so concerned about the illegality of operating outside FISA by eavesdropping on citizens without a court order, that Ashcroft and top officials of the DOJ threatened to resign.
When the seriously ill and often confused Ashcroft was in the hospital at the time, the Bushistas wanted to send Andy Card and Alberto Gonzalez, who were considered "thugs" by DOJ officials and the FBI, to visit Ashcroft in the hospital and coerce him to sign a document allowing them to commit these felonies. Comey rushed to the hospital to be present during this coercion. In fact, FBI director Mueller told his agents that Comey must be present in Ashcroft's room with Card and Gonzalez. Later, Comey would not even meet with Andy Card in Card's office without a witness present. Andy Card insisted on no witnesses being present. Pretty interesting behavior from a "legal" government.
Then the Bush Administration told Comey to do whatever was necessary to make the program "legal." It is still unclear what changes were made. This is more criminal than Watergate and the Clinton BJ put together.
