I don't understand ... the only Executive Orders I could find for the five-day period surrounding the news story were his re-upping of Clinton's EO's re: Weapons of Mass Destruction and the continued threat (and green light for bombing) Iraq.
Rumsfeld said in the press conference it was by order of the CIC to the department of defense. I guess I got the impression this was somehow different than an EO.
I'll head back to the Federal Register and try to figure out how I missed it.
Any way he did it he did it without Congress.
