it inappropriate that such a pension would be provided by a private corporation executive. That same year, legislation was first introduced to create presidential pensions, but it was not enacted. In 1955, such legislation was considered by Congress because of former President Harry S. Truman’s financial limitations in hiring an office staff The pension has increased numerous times with congressional approval. Retired presidents receive a pension based on the salary of the current administration's cabinet secretaries, which was $199,700 per year in 2012. Former presidents who served in Congress may also collect congressional pensions. The act also provides former presidents with travel funds and franking privileges. Prior to 1997, all former presidents, their spouses, and their children until age 16 were protected by the Secret Service until the president's death. In 1997, Congress passed legislation limiting Secret Service protection to no more than 10 years from the date a president leaves office. On January 10, 2013, President Obama signed legislation reinstating lifetime Secret Service protection for him, George W. Bush, and all subsequent presidents. A first spouse who remarries is no longer eligible for Secret Service protection. Presidential libraries Every president since Herbert Hoover has created a repository known as a presidential library for preserving and making available his papers, records, and other documents and materials. Completed libraries are deeded to and maintained by the National Archives and Records Administration (NARA); the initial funding for building and equipping each library must come from private, non-federal sources. There are currently thirteen presidential libraries in the NARA system. There are also presidential libraries maintained by state governments and private foundations and Universities of Higher Education, such as: the Abraham Lincoln Presidential Library and Museum, which is run by the State of Illinois; the George W. Bush Presidential Library and Museum, which is run by Southern Methodist University; the George H. W. Bush Presidential Library and Museum, which is run by Texas A&M University; and the Lyndon Baines Johnson Presidential Library and Museum, which is run by the University of Texas at Austin. Several former presidents have overseen the building and opening of their own presidential libraries. Some have even made arrangements for their own burial at the site. Several presidential libraries contain the graves of the president they document: the Harry S. Truman Presidential Library and Museum in Independence, Missouri; the Dwight D. Eisenhower Presidential Library, Museum and Boyhood Home in Abilene,
