Around August 25, 2001, future 9/11 hijacker Nawaf Alhazmi possibly calls Mohdar Abdullah, a close associate of his when he lived in San Diego in 2000, and tells him about the 9/11 attacks date. Shortly after 9/11, the FBI will question Abdullah about getting a call from Alhazmi in August; it is unclear how the FBI would have known to ask that question.
In a July 2002 interview with the FBI, Abdullah will ask if the FBI taped the phone call, suggesting that it does take place.
In 2003, Abdullah will be in a US jail, and another prisoner will claim Abdullah says he found out about the 9/11 attacks three weeks in advance.
Abdullah stops making calls from his phone after August 25, 2001.
After 9/11, Abdullah’s friends will say that Abdullah starts acting strangely around this time. [9/11 Commission, 7/24/2004, pp. 218, 531]
According to a witness, one day before 9/11, Abdullah and some of his co-workers (who are themselves radical Islamists (see Autumn 2000)) will appear to celebrate the upcoming 9/11 attacks, and one of them says, “It is finally going to happen” (see Late August-September 10, 2001).
In 2003 and 2004, more evidence will emerge that Abdullah willingly took part in the 9/11 plot, but he will be deported anyway (see September 2003-May 21, 2004 and May 21, 2004).
