Trump administration officials say they are not seeking war with Iran but haven’t ruled out using an old war powers act to hit the regime in the future.

Members of the Senate Foreign Relations Committee grilled State Department officials Wednesday on the 2001 and 2002 authorizations for the use of military force, focusing heavily on Iran. The two laws have been used to fight terrorism and engage in operations in Iraq, respectively, for nearly 20 years. As tensions with Iran continue to rise, some lawmakers are concerned the 2001 AUMF could be used to circumvent Congress should the administration decide to strike Iran.
