President Joe Biden’s new mission to hold the planners of the deadly terror attacks at the Kabul airport accountable throws an unexpected wrinkle into congressional attempts to limit the president’s war powers — something Biden himself has voiced support for in the past.

Lawmakers of both parties have sought for years to repeal the 1991, 2001, and 2002 authorizations for use of military force, which were interpreted as granting Biden’s three predecessors — former Presidents Donald Trump, Barack Obama, and George W. Bush — wide-ranging authority to pursue military action in Iraq, Afghanistan, and elsewhere without additional congressional approval. Past administrations cited the AUMFs as granting the executive branch legal authority to carry out a series of counter-terror drone strikes on targets in the Middle East, specifically the Obama- and Trump-era wars against the Islamic State of Iraq and Syria, commonly known as the terror group ISIS.
