The United States (US) government has declared a massive review of all Green Cards issued to citizens of 19 countries, following Wednesday’s attack on National Guard troops in Washington, D.C.

Donald Trump was reported to give the order on Thursday after authorities identified the detained suspect as a 29-year-old Afghan national who had previously worked with American forces in Afghanistan.

In a statement on X, the Director of the US Citizenship and Immigration Services (USCIS), Joseph Edlow, said, “I have directed a full-scale, rigorous re-examination of every Green Card for every alien from every country of concern.”
