President Donald Trump vowed on Thanksgiving to “permanently pause migration” from poorer nations in a blistering late-night, anti-immigrant screed posted to social media.

The extended rant came in the wake of the Wednesday shooting of two National Guard members who were deployed to patrol Washington, D.C. under Trump’s orders, one of whom died shortly before the president spoke to U.S. troops by video on Thursday evening.

A 29-year-old Afghan national who worked with the CIA during the Afghanistan War is facing charges for the shooting.

The suspect emigrated as part of a program to resettle those who has helped American troops after U.S. withdrawal from Afghanistan.

“Only REVERSE MIGRATION can fully cure this situation,” Trump posted on his Truth Social platform.

“Other than that, HAPPY THANKSGIVING TO ALL, except those that hate, steal, murder, and destroy everything that America stands for — You won’t be here for long!”

Trump’s threat to stop immigration would be a serious blow to a nation that has long defined itself as welcoming immigrants.
