Brewster took his case to the Supreme Court. And they turned away his challenge, based on the Speech and Debate Clause of the Constitution. The reasoning was rock solid. The freedom to speak and debate does not include the freedom to take bribes in return for corrupt acts as a Member of Congress.
The Brewster case is still good law. Rep. Jefferson is toast.

Whether or not the other Congress-critter takes bribes really doesn't have beans to do with the prerogative of the King's men to ransack the Congressional compound, and you know that.
Otherwise, you'd had Billzo's boys in there searching your offices for all those guns you keep stuffed into drawers and safes and slapping you down with the DC anti-gun law.
