It actually looks like it's not a staffer. I'm impressed.

I realize I sound curmudgeonly, so I preemptively note that for once I was actually a twitter early adopter . . but. . .isn't it sort of, well, rude to be twittering when you're meeting with the President? (Or really anyone, for that matter. . .). I mean, if I was meeting with this president, being rude would not be of great concern to me--but presumably it is to the Representative from Texas? Doesn't he have better things to be doing than thumbing out status updates?
