RE: The man who escorted Nancy all week--it's part of his duty as ?Major General? of the DC area. (not sure if that's his title . . . )
AND I was worried about the servicemen and all the steps today after the rain . . . they did great!
I just learned that he is Commander, Military District of Washington. He commands all of the troops stationed in Washington, D.C. I don't know whether it is his duty as Cdr, MDW to escort the President's widow...but it certainly seems proper to me.
