A suspect accused of shooting two U.S. National Guard troops near the White House pleads not guilty to newly filed charges, according to reporting from multiple outlets. The man, charged in connection with the incident that results in the death of one of the troops, enters the plea in response to an updated indictment. The case centers on an attack in the White House area that leaves two National Guard members shot, with one later dying from injuries. The new charges indicate prosecutors have expanded or refined the allegations since the initial filing, but specific details of the counts are not provided in the available summaries. Both outlets characterize the court action as a formal step following the new indictment, with the defendant maintaining a not-guilty plea. The matter continues through the criminal justice process, with future hearings expected to address the allegations laid out in the latest charging document.
