The president, whose own mother was a naturalized citizen, doubled down on his vow to strip some Americans of their citizenship.

President Donald Trump has doubled down on his effort to revoke the citizenship of some Americans. Following the shooting of two National Guard members by an Afghan citizen in D.C. on Wednesday, Trump declared in a post on Truth Social that he would “denaturalize immigrants who undermine civil peace.” On Sunday, a reporter questioned Trump aboard Air Force One about his promise to “denaturalize” American citizens.
