Prosecutor in terror case controversy sues Ashcroft

The lawsuit states Convertino first complained to his superiors more than a year ago about Justice's interference in the Detroit terrorism trial, saying Washington supervisors "had continuously placed perception over reality to the serious detriment of the war on terror."

The lawsuit includes excerpts of an e-mail from another prosecutor in the case that Convertino says "identified some of the gross mismanagement which was negatively impacting the ability of the United States to obtain convictions in a major terrorist case."

The e-mail from the other prosecutor shows he complained at the time that efforts by Justice's terrorism unit in Washington to "insinuate themselves into this trial are, nothing more than a self-serving effort to justify the existence" of the unit.

"They have rendered no assistance and, are in my judgment, adversely impacting on both trial prep and trial strategy," the e-mail cited in the lawsuit states.

Convertino also accused Justice officials of intentionally divulging the name of one of his confidential terrorism informants (CI) to retaliate against him.

The leak put the informant at grave risk, forced him to flee the United States and "interfered with the ability of the United States to obtain information from the CI about current and future terrorist activities," the suit alleges.

The prosecutor is being represented by the National Whistleblower Center, which has represented FBI agents and other whistleblowers in recent cases involving terrorism. Its chief lawyer successfully helped Linda Tripp win damages under the Privacy Act for the leak of information from her Pentagon personnel file after the Monica Lewinsky affair.
