Yes, if he meant that they were going to hand us over the money in advanced for a wall. I never believed that for a second, maybe some did. If he meant he will make them pay for it in the end, then yes that's still a possibility.
Again I don't necessarily believe he will build a wall, or have Mexico pay for it (initially or in a round-about way). Just trying to say just because Mexico doesn't pay for it up front, doesn't mean they won't in the end.
Like stopping free healthcare for illegals, and free housing, and any other free services. This will save A LOT!
Charging immigration fees!
There's ways to make them pay and save on what expenses we are paying for illegals now.
