Within minutes of taking the oath of office on January 20, Obama's Chief of Staff, Rahm Emanuel, issued an order suspending last-minute regulations and executive orders signed by his predecessor, George W. Bush. Some of the first actions of Obama's presidency focused on reversing measures taken by the Bush administration following the September 11 attacks. In his first week in office, Obama signed Executive Order 13492 suspending all ongoing proceedings of the Guantanamo military commissions and ordering the Guantanamo detention facility to be shut down within the year. Another order, Executive Order 13491, banned torture and other coercive techniques, such as waterboarding. Obama also issued an executive order placing tighter restrictions on lobbying in the White House, and rescinded the Mexico City Policy, which banned federal grants to international groups that provide abortion services or counseling.
