In the 1960 campaign, Lyndon B. Johnson was elected Vice President as John F. Kennedy’s running mate. On November 22, 1963, when Kennedy was assassinated, Johnson was sworn in as the 36th United States President, with a vision to build “A Great Society” for the American people. In his first years of office he obtained passage of one of the most extensive legislative programs in the Nation’s history. During World War II he served briefly in the Navy as a lieutenant commander, winning a Silver Star in the South Pacific. After six terms in the House, Johnson was elected to the Senate in 1948. In 1953, he became the youngest Minority Leader in Senate history, and the following year, when the Democrats won control, Majority Leader.
