Shortly after 9/11, Congress handed President Bush legal permission to wage war by passing the 2001 Authorization for the Use of Military Force – or AUMF. This AUMF has been used to justify endless war and has allowed congress to abdicate its constitutional responsibility in legislating wars. Instead, Congress chooses to micromanage peace processes, such as the Iran nuclear negotiations.   Now the president is using 2001 AUMF to justify a new war against ISIS. We are urging Congress to support repeal of the 2001 AUMF in order to close this chapter in American history of endless war.
