WASHINGTON, DC - MAY 25: Sen. Jeff Flake (R-AZ) (L) and Sen. Tim Kaine (D-VA) talk about their introduction of a new Authorization for the Use of Military Force (AUMF) against the Islamic State of Iraq and Syria (ISIS), al-Qaeda and the Taliban during a news conference at the U.S. Capitol May 25, 2017 in Washington, DC.
