A bill to establish a Joint Select Committee on Afghanistan to conduct a full investigation and compile a joint report on the United States withdrawal from Afghanistan.

S 170 establishes a 12-member congressional Joint Select Committee on Afghanistan to investigate the 2021 U.S. withdrawal from Afghanistan. The committee, composed of equal Senate and House members appointed by party leaders, must produce a report within 90 days detailing specific aspects of the withdrawal - including intelligence assessments, evacuation planning, timeline decisions, and communications with allies. The report must cover 23 defined elements, such as warnings about Taliban advances, National Security Council planning, and the status of assets left behind. The committee will operate for one year, with unclassified findings and a possible classified annex. This procedural bill creates a formal investigation mechanism without proposing new policy changes.
