H.R. 9435 establishes a National Security Council Fentanyl Disruption Steering Group to coordinate federal efforts against fentanyl trafficking and use. The group will be led by the President's National Security Advisor and include senior officials from thirteen agencies, including the State Department, Treasury, Defense, Justice, Homeland Security, and intelligence agencies, along with the U.S. Postal Service. The Steering Group's responsibilities include overseeing implementation of fentanyl-fighting policies across agencies, setting strategic disruption goals, identifying resource gaps, and monitoring existing task forces and initiatives to eliminate duplication. Within 60 days of enactment and annually thereafter, participating agencies must report their fentanyl-related initiatives to the group, and the Steering Group must submit annual reports to Congress describing public-private partnership strategies for combating fentanyl trafficking. The bill does not specify dedicated funding amounts or target timelines beyond the reporting deadlines.
