He insists he’s going to build a wall and make Mexico pay for it — eventually.

President Trump took to Twitter on Sunday morning to push his plan for a wall on the Mexican border, insisting that our southern neighbor will fund it one way or another.

“With Mexico being one of the highest crime Nations in the world, we must have THE WALL. Mexico will pay for it through reimbursement/other,” Trump tweeted.

The declaration comes after Trump this week threatened to shut down the government if Congress doesn’t fund the wall — despite his previous insistence that Mexico would be the one to fund the barrier.

Asked Sunday whether Trump’s threat meant he is conceding that Mexico is not going to pay for the wall — as President Enrique Peña Nieto has long said — White House aide Tom Bossert also claimed that’s not the case.

“What we’ll do here is go through the mechanism of getting the initial money that we need for that capital project from Congress through an appropriations process and we’ll responsibly construct a barrier on the border,” Bossert said on ABC’s “This Week.”

“As we work with the Mexicans and other policies and trade policies and such, we’ll determine ways for us to make that right.”

Trump followed his wall tweet up with another threatening to pull out of the North American Free Trade Agreement.

“We are in the NAFTA (worst trade deal ever made) renegotiation process with Mexico & Canada.Both being very difficult, may have to terminate?” Trump wrote.
