The Department of Homeland Security says a man who fired at officers in Pennsylvania's state capital before he was shot and killed Friday was a naturalized U.S. citizen who was admitted to the country from Egypt on a family-based immigrant visa.
Acting DHS Press Secretary Tyler Q. Houlton says Saturday that "the long chain of migration" that led to Ahmed Aminamin El-Mofty's admission to the U.S. was initiated years ago by a distant relative.
Authorities say El-Mofty fired at a Capitol police officer Friday and later at a state trooper, wounding her. El-Mofty then attacked other officers with two handguns and was killed.
Houlton says incidents like the one involving El-Mofty "highlight the Trump administration's concerns with extended family chain migration." He says chain migration and the diversity visa lottery program have been exploited by extremists.
