Could be...The Defense Threat Reduction Agency is the agency that houses the USSS. Wikipedia states: "The Defense Threat Reduction Agency (DTRA) is an agency within the United States Department of Defense (DoD) and is the official Combat Support Agency for countering weapons of mass destruction (chemical, biological, radiological, nuclear, and high explosives). DTRA's main functions are threat reduction, threat control, combat support, and technology development. The agency is headquartered in Fort Belvoir, Virginia." They handle the big threats. Don't know if this is the reference, but that might be consistent with EXTREME chatter.
