This just came across the AP wire:
The 2002 investigation determined that an e-mail address once used by Berg apparently was obtained by the Moussaoui acquaintances while Berg was briefly an engineering student at the University of Oklahoma in 1999.
Moussaoui came to the United States in February 2001 and enrolled at a flight school in Norman, Okla., also the home of the university. The Moroccan-born French citizen left that flight school later in 2001 to attend one in Minnesota, where he was arrested on an immigration violation shortly before the Sept. 11 attacks.
Ashcroft told reporters there is no evidence that Berg knew Moussaoui or any of Moussaoui's contacts in Oklahoma.
Moussaoui is Moroccan-born? Last May, Casablanca, Morocco was rocked by a series of simultaneous bombings by al-qaeda terrorists - and the majority of the MANY suspects in the March 11 Madrid train bombings are Moroccans, too.
