GW Bush never revised this. If you can find a link I’ll gladly stand corrected.

From all the articles I've read GW Bush amended it twice.

The original EO dealing with national defense resources preparedness was issued in 1939 (EO 8248) according to the National Archives. It has been superseded a number of times, starting in 1951 by nearly every President through Bill Clinton, and amended twice by George W. Bush.

I believe the years Bush amended it were 2003 and 2008.
