Not possible...just be veto’d. Anyway his promises are MEANINGLESS without the ability to remove him if he ‘changes his mind’.
The House could eliminate funding since they control the purse. They won’t.
We haven’t seen a good Override in years!! In fact, we never even hear about anymore. It is like we just give up.
I guess he could stop funding them. But how likely is that going to happen. Especially after backstabbing repukes just gave Biden 1.7 trillion to sabotage anything the new House can do its first year?
