B-but, but… The Burn Bags??? The grand jury in Florida??? The conspiracy against rights???
Kash gotta stick around to cover for that stuff, right?
(If you don’t know what I’m talking about, keep it that way. This is like the dumbest bullshit I’ve ever heard, and I’ve heard a lotta bullshit. )

The speech and debate clause is separate from the arrest clause. The Treason exception only applies to the first part.
Additionally, Treason has a definition elsewhere in this document, and just giving any kind of speech doesn’t meet the standard.
It would be pretty hard to claim that any kind of speechifying amounts to “Aid and Comfort”, especially if you can’t identify the “Enemy” in a time when the nation is at peace.
Now the first amendment does apply here, but I expect a legal defense to go to this speech and debate clause first, then 1st amendment. Because 1st amendment has a bunch of exceptions of the “yelling fire in a crowded theater” type, but speech and debate is going to be more ironclad. Once you convince a court that you were doing Congressional speech or debate, then the only discipline you can face is from your chamber’s rules, period.
