A criminal probe is underway in the Eastern District of Pennsylvania, where Carla Martin was licensed to practice law, pertaining to her unauthorized communications with FAA witnesses in the Zacarias Moussaoui trial:

Meanwhile, federal prosecutors in Philadelphia are investigating a government lawyer who nearly derailed Moussaoui's sentencing trial by coaching witnesses and lying to his defense attorneys. The criminal investigation of Transportation Security Administration lawyer Carla J. Martin was revealed in the recently unsealed transcript of a closed March 21 hearing in the Moussaoui case.

At that hearing, Brinkema disclosed that she had been "advised by the U.S. Attorney's office that there may very well be a prosecution of her, at least they're looking at the possibility." Rob Spencer, the lead prosecutor in Moussaoui's case, said the matter was referred to the Eastern District of Pennsylvania, where Martin is a member of the bar. Prosecutors in Alexandria decided to take no part in the investigation.

Update: Cryptome has the transcript of the March 14 hearing (html) where Martin was present and the Judge said it was one of the most egregious violations she had seen as a judge. There's lots of good stuff in the transcript.
