Well, when was Wilson possibly in the Green Room with Vallely? In reverse chronological order:
January 10th, 2003 (Vallely, Wilson). Wilson was on John Gibson’s show this day. Which is why Gibson has similar recollections to General Vallely. Vallely was on Cavuto which airs right before Gibson’s show.
November 18, 2002 (Vallely, Wilson). Vallely was scheduled for 1:10, Wilson was to be on after 3:00 PM.
October 1, 2003 (Vallely, Wilson). Wilson was on Fox and Friends in the morning, Vallely on Cavuto. Depending on when Vallely came in to tape his section they could have met up.
September 12, 2002 - they were on the same show at 3:00 PM.
August 20, 2002 (Vallely, Wilson). Wilson was on Greta and Vallely on Cavuto. Depending on when/if things were taped the could have run into each other.
