Senators on Tuesday gamely struggled to see if there was a way to set aside longstanding partisan differences over a new authorization for use of military force amid expanding military campaigns in Syria and Iraq, and under a new president who has delegated significant tactical authority to his commanders.
The Trump administration is waging its anti-ISIS campaign under the authority of the 2001 AUMF, which Congress passed shortly after the September 11 attacks. Sixteen years later, experts on both sides of the aisle increasingly agree the authorization (PL 107-40) has been stretched beyond almost all legal recognition to justify the occasional air strike on Bashar al-Assad’s forces in Syria and even far-flung groups like Al-Shabab in East Africa.
