Tucker Carlson joined "Fox & Friends" this morning to discuss the brewing fight between President Donald Trump and Democrats on the proposed Mexican border wall.

Earlier in the show, Attorney General Jeff Sessions said Democrats will support any border security measures, but none that would actually work and work.

"[The wall] will be the end of illegality," said Sessions, cautioning Democrats against threatening a government shutdown to block funding for the barrier.

Carlson said Democrats are opposed to the border wall because it will work, likely curbing the flow of cheap labor and prospective new Democratic voters.

"It costs too much? Really? From people who don't care what anything costs? That's not a real argument. Their real problem with it is this may stop the flow of cheap labor and new voters," he said.
