U.S. officials have arrested and charged two men with assaulting U.S. Capitol Police officer Brian Sicknick with bear spray during the Jan. 6 riot, but they do not know yet whether it caused the officer's death. George Tanios, 39, of Morgantown, West Virginia, and Julian Khater, 32, of Pennsylvania, were arrested Sunday. They were expected to appear in federal court Monday. The idea that Sicknick died after being sprayed by a chemical irritant has emerged in recent weeks as a new theory in the case. The arrests are the closest federal prosecutors have come to identifying and charging anyone associated with the deaths that happened during and after the riot. Five people died, including a woman who was shot by a police officer inside the Capitol. Story: https://www.whas11.com/article/news/n...
