Cole Allen, 31, pleads not guilty in a federal district court in Washington, D.C., where he appears before U.S. District Judge Trevor McFadden. Both outlets report the plea is entered during his court appearance in the nation’s capital. The case centers on allegations related to the shooting at a White House press gala. The reports describe the proceedings at the time of the plea but do not provide additional detail on the charges, the timeline of the incident, or any statements made by prosecutors or the defense beyond the plea itself. Following a not-guilty plea, the case proceeds through the federal court process, including future hearings and potential pretrial proceedings. As presented in these accounts, the key development is the suspect’s formal response in court to the charges brought by federal authorities. No further agreements, bail details, or trial dates are included in the provided summaries.
