Way to go, Pappy. If it were me, I don't know if I could let go of Melania's hand, or even wash it again. You should be very proud to have a kid in the NSA.
I am a bit surprised that the soldiers did not remove their covers when greeting the First Lady. Has that protocol changed? I remember when I met President and First Lady Johnson, we were ordered to remove our covers. (Maybe they don't call caps covers anymore.)
