The Gravel and Brewster cases: can Rep. Jefferson's papers be seized?

An excellent law review article on U.S. v. Brewster, 408 U.S. 501, is by Ervin, "The Gravel and Brewster Cases: An Assault on Congressional Independence," 59 Va. L. Rev. 175. I've been skimming it; if I find anything interesting I'll pass it on.

I note also that I misspoke below: U.S. v. Johnson was in fact affirmed by the U.S. Supreme Court in 383 U.S. 169. Johnson could not be prosecuted for being bribed to give a favorable speech before the House.
