had also been kept from Truman). At the time he said, "I felt like the moon, the stars and all the planets fell on me." Determined that no future vice president should be so uninformed upon unexpectedly becoming president, Truman made the vice president a member of the National Security Council, a participant in Cabinet meetings and a recipient of regular security briefings in 1949. The stature of the vice presidency grew again while Richard Nixon was in office (1953–1961). He attracted the attention of the media and the Republican Party, when Dwight Eisenhower authorized him to preside at Cabinet meetings in his absence and to assume temporary control of the executive branch, which he did after Eisenhower suffered a heart attack on September 24, 1955, ileitis in June 1956, and a stroke in November 1957. Nixon was also visible on the world stage during his time in office. Until 1961, vice presidents had their offices on Capitol Hill, a formal office in the Capitol itself and a working office in the Russell Senate Office Building. Lyndon B. Johnson was the first vice president to be given an office in the White House complex, in the Old Executive Office Building. The former Navy Secretary's office in the OEOB has since been designated the "Ceremonial Office of the Vice President" and is today used for formal events and press interviews. President Jimmy Carter was the first president to give his vice president, Walter Mondale, an office in the West Wing of the White House, which all vice presidents have since retained. Because of their function as President of the Senate, vice presidents still maintain offices and staff members on Capitol Hill. Another factor behind the rise in prestige of the vice presidency was the expanded use of presidential preference primaries for choosing party nominees during the 20th century. By adopting primary voting, the field of candidates for vice president was expanded by both the increased quantity and quality of presidential candidates successful in some primaries, yet who ultimately failed to capture the presidential nomination at the convention. At the start of the 21st century, Dick Cheney (2001–2009) held a tremendous amount of power and frequently made policy decisions on his own, without the knowledge of the president. During the 2008 presidential campaign, both vice presidential candidates, Sarah Palin and Joe Biden, said the office had expanded too much under Cheney's tenure;
