Ok, it isn't so.
:o)
First of all, if true, that would not comport with Laura identifying herself as "a desperate housewife" whose husband is as dull as a rock, and we all know that she meant every word of that comedy routine, don't we, because some FReepers have told us so.
But second of all, forget first of all, I somewhat doubt if they think of Air Force One as the appropriate place. They seem like people who do highly respect the Presidency and the symbols of the Presidency. They seem very businesslike about their actual jobs. And they have plenty of other appropriate places, don't they, including their own living quarters at the White House, Camp David, a 1600 acre ranch, etc.
Now Bill Clinton would (not with Hillary, though), just for the same reason he dallied with Monica in the Oval Office...as he himself said in an interview, he did it for an inexcusable reason, and that was "just because I could".
I cannot prove one way or the other about G & L and Air Force One. Just expressing an opinion that I would tend to doubt it. Hopefully, if I am wrong about that, their privacy will be maintained and such details will indeed remain private.
Eh... LOL. Please, don't try.
facetious- Playfully jocular; humorous. As in facetious remarks.
