No Adversarial AI Act

S 2177, the "No Adversarial AI Act," prohibits U.S. government agencies from acquiring or using artificial intelligence (AI) developed by "foreign adversaries" (defined as entities linked to countries deemed national security threats). Within 90 days of enactment, agencies must review and remove such AI from their systems, using a publicly listed catalog created by the Federal Acquisition Security Council (updated every 180 days). Exceptions allow limited use for scientific research, security testing, counterterrorism, or mission-critical functions, requiring written notice to Congress. The law directly affects federal agencies and foreign AI developers designated as adversaries, focusing on restricting government procurement of high-risk AI tools.
