Where does it say that he can't? Get over yourself.

They owe us Trillions for the cost of their invasion and occupying our country. Trump is only demanding that they pay back a few billion to pay for a way to keep their @sses out. Sneak into their country and see what happens when you get caught.

He can charge them a fee at the border and they WILL pay for the wall. Too bad that they didn't patrol their borders better.

THey are taking American jobs
They are jumping the line of proper immigration applicants
They are bringing diseases into our country.
They are smuggling drugs into our country.
They are committing crimes in our country
They are costing America billions every year.
They are bumping Americans out of college seats
They are stealing identities
Many of them are not paying taxes
They are causing Americans that hire them to commit crimes by hiring illegals.

Time to clean up the border and protect our fellow Americans.
