As a lobbyist:
I sat down in the subway that runs beneath the Capitol, and across from me was none other than former Senator Larry Craig.
The Idaho Republican greeted me with a smile and told me that he was now back "making the rounds" to see his former Senate colleagues for his clients.
Craig is now a lobbyist - and Senate rules prohibit former senators from lobbying any lawmaker or aide for two years.
He's probably better paid this time too, so perhaps he can afford a better alternative to airport bathrooms when it comes to getting his jollies.
