Secretary of Defense James Mattis and Secretary of State Rex Tillerson testified before the Senate Foreign Relations Committee on Monday to give the Trump Administration’s stance on calls for a renewed Authorization for the Use of Military Force, or AUMF.

Both Mattis and Tillerson advocated leaving the AUMF in its current form, and warned against repealing it.

Leading Senators like John McCain (R-Az.) and Tim Kaine (D-Va.) are using events like the ambush in Niger of Special Forces personnel, and the rise of ISIS affiliates worldwide as justification for a new discussion on the President’s ability to wage war with what some see as “blanket approval” from Congress.

As we face a wide array of threats abroad, it is perhaps more important than ever that we have a sober national conversation about Congress’ constitutional role in authorizing the use of military force,” Republican Bob Corker, the chairman of the Senate Foreign Relations Committee, said in a statement.
