I believe they need 2/3 vote of the Senate to ratify treaties.
“He shall have Power, by and with the Advice and Consent of the Senate, to make Treaties, provided two thirds of the Senators present concur;...” Art2 Sec2
So even trying to implement that I do not think will pass the Senate and definitely NOT the house.
I do not believe, or at least I hope, this will not be attempted by some executive order...even those have to have some sort of enabling legislation. Otherwise he could just do what he wanted, the heck with the constitution,
Hey....wait a minute....
“I believe they need 2/3 vote of the Senate to ratify treaties.”
They only need 2/3rds of those present and quorum of the Senate is 51, meaning they only need 34 to pass it. That’s it. Those are the numbers. They don’t even have to hold the quorum in the Senate chambers. They can meet privately wherever they desire.
The House is not involved with treaties in any way.
