You don’t get. This has nothing to do with Trump or Obama.
This is a deal between democrats and republicans in congress. Trump is probably finding out about it right now just as you are.
He has a choice. Veto it and have them override his veto, making him look weak. Or sign it and focus on the positive aspects like 1.5 billion for border security.
Do you think signing this monstrosity makes Trump look strong??
