President Trump said he’d be willing to “shut down” the government unless Democrats in Congress help pass immigration reform, including funding for his long-touted border wall, saying “we need great people coming into our Country!”

“I would be willing to ‘shut down’ government if the Democrats do not give us the votes for Border Security, which includes the Wall! Must get rid of Lottery, Catch & Release etc. and finally go to system of Immigration based on MERIT!,” he posted on Twitter Sunday. “We need great people coming into our Country!”

Trump spent much of the weekend at his golf resort in New Jersey railing about Democrats not supporting his immigration policies, saying all they do is “Resist” and “Obstruct,” while claiming they want “Open Borders.”

Earlier Sunday, he said “there are consequences when people cross our Border illegally,” referring to the separation of children from their parents, and called on Congress to repair “the DUMBEST & WORST” immigration laws in the world.

He concluded with a campaign message: “Vote ‘R.'”

His administration has come under blistering criticism for separating children from their parents over its “zero tolerance” immigration crackdown to deter immigrants from trying to cross the border illegally.

The government in a court filing said it had met a Thursday deadline set by a federal judge by reuniting more than 1,800 children with their parents or guardians.

But another 711 children would remain separated because their parents either had been deported or had criminal records.
