On Thursday, federal authorities arrested Ashton Hamed Ellaboudy, an employee at the Department of Energy’s Hanford nuclear site in Richland, Washington. The Department of Justice has charged Ellaboudy with attempting to provide material support or resources to the Houthi movement, an Iranian-backed group based in Yemen that the U.S. government has designated as a terrorist organization.

According to federal prosecutors, the investigation focused on Ellaboudy’s alleged efforts to assist the group. While the Department of Justice has confirmed the charges and the location of the arrest, specific details regarding the nature of the support he allegedly attempted to provide or his specific role at the Hanford facility remain limited. The Hanford site is a former nuclear production complex that is currently undergoing extensive environmental cleanup. Federal officials have not yet released information regarding whether Ellaboudy had access to sensitive nuclear materials or if his alleged actions posed a direct security threat to the facility itself. The case is currently moving through the federal court system, where Ellaboudy will face the charges brought by the Justice Department.
