This bill restricts the authority of federal law enforcement agencies to operate in local areas without permission from state or local leaders. Specifically, it requires the Drug Enforcement Administration to focus only on drug-related investigations, prevents the U.S. Marshals Service from deputizing local or other federal officers without approval from the governor or tribal leader, and prohibits the Department of Homeland Security from deploying additional officers to protect federal property in areas experiencing protests unless the state or local chief executive requests it. The legislation primarily affects federal law enforcement agencies and their interactions with state and local governments during protest situations. The bill includes a narrow exception for the Federal Protective Service, which transferred to the Department of Homeland Security under the 2002 Homeland Security Act and can continue normal operations. The bill does not contain specified funding amounts or implementation timelines.
