The article is pretty bizarre. The tone of the article and some of the people discussed make it sound like the Congressfolk were caught shooting up heroin or something instead of…swimming? I’m half convinced “swimming” must be a euphemism for something I’m unaware of.
I rather wish lobbyist paid trips by Congress and their staffs were illegal. But they aren’t, so if Congresscritters are going to take them, they mind as well have a good time.
