The problem is a Billionaire could walk in with a single check for the whole thing, but it would have to get deposited into the Treasury.
The only way to get the money out of the Treasury (even though it is specifically for the wall) is for Congress to appropriate the expenditure.
Chuck has said they will not do this.
Yep. It is not as if they don’t already have the money for it. They just refuse to spend it. They’d rather use the money on vote-buying welfare programs.
That is exactly what I have been wondering. The courts will try to say this is just the POTUS trying to run around the legislators.
