Jefferson's pleas and the search warrant application are here BTW: http://www.scotusblog.com/movabletype/archives/2006/05/the_hill_search.html
"FBI agents barred both the House general counsel and the Sergeant at Arms from the rooms it was searching. "

Lawyers tend to see this strictly legally (of course!): that as long as the privileged records aren't used in court it's OK to look at them if you have a warrant.
But the Debate Clause is different from any other legal "privilege" ( none of the others are in the Constitution) and has a very different purpose than the others.
I think you'll find that slightly stricter protocols such as I laid out in post 251 will come of this, and it will be a good thing.
Thanks for the link. I think you are correct about the eventual outcome. Along with Congressman Jefferson spending some much deserved quality time at Club Fed of course. Hopefully along with a bunch of other involved Congress Critters, staffers, "lobbyists" etc. For I doubt very much this was a solo affair.
