Are you seriously thinking he wouldn't?
He might fantasize about it, but it's risky with no real career upside. If he's caught, or even suspected, he'll never work in this town (DC) again. If he isn't caught, sure he feels pretty smug, but it's not something he can brag about to get work or social stature. Heck, it's not even something he can tell to the girls (not even Claire Shipman).
