You're bad at word problems too aren't you? NAFTA was redone. We now receive more money from Mexico. That money could be used to build the wall, but Democrats want to give it back to Mexico.
"BUILD THE WALL!"; "MEXICO WILL PAY FOR IT!"; OK, MEXICO WILL PAY US BACK. OK, We'll make a deal with Mexico and the savings will pay for it. WE NEED A WALL! OK, taxpayers will pay for it. CONGRESS WON'T FUND IT. SHUT DOWN THE GOVERNMENT!
