In Roll Call (sub.req.), Paul Kane and John Bresnahan are fleshing out the key detail about the compensation package the Copeland Lowery lobbying firm paid ex-lobbyist Jeff Shockey after he went back to work for Appropriations Chairman Jerry Lewis (R-CA) on Capitol Hill: his post-employment compensation was tied to how much his former clients paid his former firm after he was already working on the Hill.

This is an admittedly complicated story. And if it's new to you, I run through the details at more length in this post from over the weekend.

But the bottom line is that the clients Shockey was paid to lobby for through 2004 had a way to put more money in his pocket while he was helping run the Appropriations Committee as its deputy director in 2005.

We'll have a lot more on this tomorrow at TPMmuckraker.com.
