I don’t believe Sniffer is even CAPABLE of negotiating or even understanding he details of the proposal given by the House. All he can do is say “No” and let whoever is REALLY controlling the agenda dictate what he has to say.
The Center for American Progress runs Biden. That is where KJP is from. They HATE America.
I don’t think Sniffer can say “no”, he can only sign what is in front of him. And, no, I don’t think he in charge of anything.
