In 2001, President George W. Bush was unable to obtain sufficient Democratic support for his tax cut proposals. As a result, the Bush tax cuts of 2001 and 2003 were each passed using reconciliation, which required that the tax cuts expire within the 10-year budget window to avoid violating the Byrd rule in the Senate. The status of the tax cuts would remain unresolved until the late 2012 "fiscal cliff," with a significant portion of the cuts being made permanent by the American Taxpayer Relief Act of 2012, passed by a Republican Congress and signed by President Barack Obama.
