"The administration supports the repeal of the 2002 AUMF, as the United States has no ongoing military activities that rely solely on the 2002 AUMF as a domestic legal basis, and repeal of the 2002 AUMF would likely have minimal impact on current military operations," the administration said in a policy statement.
The U.S. Constitution gives the power to declare war to Congress. However, that authority has gradually shifted to the president as Congress passed AUMFs that did not expire - such as the 2002 Iraq measure, as well as one that allowed the fight against al Qaeda after the Sept. 11, 2001, attacks.
A handful of members of Congress have been pushing for years to repeal, and possibly replace, the authorizations.
The administration statement said Biden is committed to working with Congress to ensure that outdated authorizations are repealed and replaced with "a narrow and specific framework" to ensure the country can continue to protect itself.
The House of Representatives is due to vote this week on the legislation to repeal the 19-year-old Iraq war authorization, which was introduced by Democratic Representative Barbara Lee. There was no immediate word on when the Senate might consider it.
Lee has long sought to hold presidential military powers in check. She was the only member of Congress to oppose the AUMF passed days after the Sept. 11 attacks, saying it provided too much of a "blank check" to allow the president to pursue military action.
