Civics: How the 2002 Iraq AUMF Got to Be So Dangerous, Part 1: History and Practice

Scott R. Anderson

For the past two years, Congress has been on the verge of a step that it hasn’t taken in more than half a century: the repeal of an outstanding war authorization. Several decades-old authorizations are nominally on the chopping block. But only one has been the subject of substantial debate: the repeal of the Authorization for Use of Military Force (AUMF) Against Iraq Resolution of 2002 that authorized the 2003 invasion of Iraq.

Legislation rescinding the 2002 AUMF was among the first House measures introduced in the 117th Congress in 2021. A few weeks later, the Senate reintroduced its own longstanding bipartisan proposal to repeal both the 2002 AUMF and the separate 1991 AUMF that authorized the first Gulf War. A bipartisan House majority voted 268-161 in support of repeal in the summer of 2021. The Biden administration even endorsed the move, providing assurances that it “would likely have minimal impact on current military operations,” as “the United States has no ongoing military activities that rely solely on the 2002 AUMF as a domestic legal basis.” And after holding an additional hearing on the matter, the Senate Foreign Relations Committee voted 14-8 to favorably report that chamber’s own repeal measure to the broader Senate a few months later.

But since then, progress on the proposal has flagged. Despite discussions among Senate leadership, the Senate proposal has yet to receive a floor vote. Last year, the House incorporated repeal into its version of the 2022 National Defense Authorization Act (NDAA), but the Senate did not, leading the conferees to omit it from the final version that was enacted into law. This year, the same scenario may yet repeat itself: while the House has included repeal in its version of the 2023 NDAA, it’s not yet clear whether a parallel measure will make its way through the complex NDAA process being pursued by the Senate. If it does not, then the robust bipartisan coalition of Senators supporting repeal will have to find another legislative vehicle—or make the difficult case that a freestanding bill warrants some of the extremely limited floor time both chambers have left before this Congress ends. Otherwise, they will have to start the process all over again when the 118th Congress sits in January next year.
