Harry Truman: “I think very highly of Brier McMahon.”

As far as I am concerned.

No more than one National Security Medal shall be awarded to any one person, but for subsequent services justifying an award, a suitable device may be awarded to be worn with the Medal.

There is hereby established a medal to be known as the National Security Medal with accompanying ribbons and appurtenances.

The course of action you recommend has my approval.
