The State Department is harnessing the power of artificial intelligence to go after visa recipients in the United States who appear to express sympathy for Hamas and other terrorist groups.

Under a “catch and revoke” program that Secretary of State Marco Rubio has launched but not yet announced, the Trump administration is scanning social media posts to identify non-U.S. citizens residing in the country who are believed to support Hamas, according to Axios. The State Department would not comment on the program or its use of AI.
