President Trump on Friday declared that the US was “full” and that asylum seekers and other immigrants heading to the southern border should pack up and go home.

The commander-in-chief blamed Democrats for the recent surge in migrant families from Central America, with apprehensions nearing an estimated 100,000 in March alone, a number that has swamped detention facilities.

“It is a colossal surge and it is overwhelming our immigration system and we can’t let that happen. The system is full. We can’t take you anymore,” the president said during an appearance with federal and elected officials near the border in southern California.

“Illegal migration, we can’t take you anymore. Our country is full. The sector is full. We can’t take you anymore. Turn around, that’s the way it is.”

The president asserted that he was right to declare a national emergency at the border and that “everyone” knows it — even Democrats who opposed the move.

Trump was set to visit a section of border fencing in Calexico that had been replaced, referring to it as a “new” section of his long-promised border wall.

“We’re building a lot of wall. Going to see a piece of it today,” the president said.

But the fence that Trump planned on touring is a 2-mile section that was a long-planned replacement for an older barrier, rather than a new wall.

The White House said the barrier was marked with a plaque bearing Trump’s name and those of top homeland security officials.
