Last updated Apr 5, 2026|Official source

Summary

The President must, no later than 180 days after December 20, 2019, and every 180 days after that, send a report to the congressional defense committees, the Senate Committee on Foreign Relations, and the House Committee on Foreign Affairs about actions taken under the Authorization for Use of Military Force (Public Law 107–40) and about any U.S. role in leading, coordinating, moving, or accompanying foreign military forces when those forces were in combat or clearly close to combat during the prior 180 days. Each report must say which countries or groups were targeted under the AUMF and why that law applies, give an intelligence judgment about the risk each poses to the United States, list countries where operations happened and why (including whether they were active combat zones), describe the status and likely scope and length of operations, name partner forces and countries where U.S. forces worked with foreign forces in combat or imminent combat and say whether those actions were under the AUMF and whether the enemy forces are covered by it, and describe what each coalition partner contributed (money, equipment, training, troops, and logistics). The parts on which countries/groups were targeted and the intelligence assessment must be unclassified. If U.S. forces enter hostilities under other laws or constitutional authority, the President must follow these reporting rules, the War Powers Resolution (50 U.S.C. 1541 et seq.), and any other applicable law. At least once in each 180-day period the President must also give a briefing to the same committees about the report.
