Three days after 9/11 Congress quickly passes the Authorization for Use of Military Force (AUMF) which gives President Bush the power to:
". . . use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons."
U.S. Attorney General Alberto Gonzalez later claims the AUMF authorized wholesale warrantless wiretapping.
