Hmmm...the magic of Google:
Here is the exact process Truman went thru..., with a crucial item being:

"January 12, 1949: The Fahy Committee holds its first meeting with President Truman and the Secretaries of the Army, Navy, Air Force and Defense. "I want the job done," the President said, "and I want it done in a way so that everyone will be happy to cooperate to get it done."

Tha may be the meeting I read about.

Many have asked why this would not work fof DADT.
