Omar Al-Bayoumi

From 911Encyclopedia:

During November 2002, law-enforcement authorities renewed accusations on Omar al-Bayoumi, one of two Saudi nationals who indirectly received thousands of dollars from Princess Haifa al-Faisal, wife of Ambassador Prince Bandar bin Sultan, as the major contact for terrorists operating out of "sleeper cells" in San Diego.

The FBI was furthermore investigating checks written on Princess Haifa's bank account to Majida Ibrahim Ahmad, wife of Saudi national Osama Basnan, a close confidant of al-Bayoumi. The checks included monthly payments of $2,000 between November 1999 and May 2002 and at least one for $15,000 in April 1998. 

As reported, the cash was to help defray the cost of treatment for a thyroid condition, but several of the checks were endorsed to Basnan and later diverted to an account maintained by al-Bayoumi, authorities said. The checks began before the arrival in California of two September 11 hijackers, Khalid Almihdhar (->) and Nawaf Alhazmi (->), identified as being aboard American Airlines Flight 77 when it crashed into the Pentagon.
