Austin mass shooter Ndiaga Diagne entered U.S. during Clinton admin, became citizen under Obama – despite string of busts | 1 March 2026 | The gunman behind Austin’s possible terror-related mass shooting entered the U.S. and cemented his legal immigration status under Democratic administrations — despite a growing criminal record. Senegalese national Ndiaga Diagne, 53, arrived in America on March 13, 2000, on a B-2 tourist visa during the Clinton administration, a source familiar with his immigration history told The Post on Sunday. Diagne — who killed two people and wounded 14 more during his rampage outside a Texas bar early Sunday — then became a lawful permanent resident on an IR-6 visa in June 2006 when he married a U.S. citizen, the source said. He had already racked up at least one arrest before that, for illegal vending in June 2001 in New York City, law-enforcement sources said. He then went on to lodge a string of other arrests in the Big Apple between 2008 and 2016, but that didn’t stop him becoming a naturalized U.S. citizen on April 5, 2013, sources said.
