No one was more surprised than Rep. Barbara Lee (D-Calif.) on Thursday when her language revoking the administration’s war authority was unexpectedly backed by Republicans and added to a must-pass defense spending bill.

“Whoa,” Lee wrote on Twitter following a voice vote that pushed through her amendment to sunset the 2001 Authorization for Use of Military Force (AUMF).

Lee’s measure, which prompted applause when it was adopted in the House Appropriations defense bill, would revoke the AUMF eight months after the passing of the defense act, forcing Congress to vote on a new law in the interim.
