Yeah true, but that means government is shutdown, something Trump wants to avoid. You veto something with such strong support it's going to be bad.

Trump has bad options. He is actually pushed to sign the bill, agreeing that in the bill you need permission from the local community to build the wall. I don't think many local communities want the wall so the wall might not even be built. On top of that, he wants to declare national emergency to get the funding and even if he wins, the wall might not be built because again, you need permission from the local community. He's going to go nuclear, try to get bags of money for a wall but then no community wants to build it. Signing the bill undermines his ability to have a valid national emergency declaration in the first place.

Whoever his advisors are, he needs to stop listening to them and fire them. This is actually the worst deal I've seen that I can remember.
