President Trump said late that he would suspend immigration from developing nations to the U.S.  In a post to Truth Social, Mr. Trump wrote that he "will permanently pause migration from all Third World Countries to allow the U.S. system to fully recover."  As he should.

     The declaration follows the shooting in downtown Washington, D.C., just blocks from the White House, in which a National Guard member was killed and a second Guard member critically wounded. The suspect detained in the shooting has been identified as a 29-year-old Afghan national who was admitted to the U.S. in September 2021, along with thousands of other Afghan refugees, a month after the U.S. withdrew its troops from Afghanistan.  

     Since the shooting, the Trump administration has taken an aggressive stance on U.S. immigration policies it says are to blame for allowing the suspect into the U.S., and has vowed to change them. The president did not clarify when such a move might take effect or how the pause would be implemented. He also did not disclose which countries would fall under such a designation.

     CBS News has reached out to the White House for clarification.

The president also wrote that he would "terminate" the status of millions of migrants admitted under former President Joe Biden's administration and "remove anyone who is not a net asset to the United States."

     He said he would end "Federal benefits and subsidies" for "noncitizens" and deport foreign nationals who are determined to be a "security risk, or non-compatible with Western Civilization."  Earlier, the Trump administration said it would be conducting a "full-scale, rigorous reexamination" of all green cards for every immigrant from 19 countries "of concern."
