Al Hamzi and al Midhar connect to the Iraqi who picked them up at the airport in Malaysia - the same Iraqi who was caught later by Jordan and when his effects were searched there and in other places the contact info for the terrorists who hit us in 1993 were found, etc.
al Midhar’s related to al Hada:
The NSA began tracking al Qaeda’s Ahmed Mohammad ali al Hada in 1999 using info from the 1998 US Embassies bombing plots.
