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.
Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the Testimony of two Witnesses to the same overt Act, or on Confession in open Court.
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.






Oklahoma has a stricter anti-establishment clause (separating church and state) in its state constitution than the US constitution. This happened because OK wrote its constitution in the 1900s in the midwest.
Having said that the Bible plan was absolutely horrendous. They were going to buy Trump-branded Bibles for $50 a piece, which contained just the public-domain King James text, and the US constitution. Complete grift.
