Yes...
He was the Paintball Cell’s Ali A Timimi.
Timimi is unique because of the incredibly long prison sentence he received in comparison to other terrorist subjects and the press’s incredible disinterest in it.
Ali Al-Timimi, an Islamic scholar whose home was also searched - "12 Washington-area Muslims investigated for alleged terrorist ties," By Karen Branch-Brioso, St. Louis Post-Dispatch, Thu, Jun. 12, 2003
Most early reporting made no mention of al-Timimi as a scientist, just as an Islamic scholar.
A FR poster by the name of Zac and Pook brought up al-Timimi as a Ft Detrich character, I think he cited an NPR story.
Another article said al Timimi had attended the microbio program at George Mason U.
His case is intertwined in the terror charity case of the Benevolence International Foundation.
Ali Timimi allegedly had Sheikh al-Hawali's letters hand-delivered to every member of congress on the "first anniversary of the anthrax letters," whatever date that's supposed to mean- the date they were sent, the date that one was first received in FL, in congress, in the press or what exact date I don't know. That's from something Zac and Pook posted so I don't know the source, been too busy to find out. The letters were said to be a warning against invading Iraq. Perhaps that was what Bush meant when he was talking about blackmail.
