Two Jordanian nationals were known to federal authorities before they attempted to breach security at Quantico Marine Corps Base.
The first unidentified man was admitted into the U.S. on a student visa on September 11, 2022, which expired 18 weeks later, on January 14, 2023. The second man crossed the U.S. from Mexico to California six weeks ago, on April 8, 2024. The next day, the U.S. Border Patrol issued a notice to appear before an immigration judge and, later that day, released the man into the U.S.
