The presidency of John F. Kennedy began at noon EST on January 20, 1961, when Kennedy was inaugurated as the 35th President of the United States, and ended on November 22, 1963, upon his assassination, a span of 1,036 days. A Democrat from Massachusetts, he took office following the 1960 presidential election, in which he narrowly defeated Richard Nixon, the then–incumbent Vice President. In the aftermath, he took full responsibility for the failure, saying: 'We got a big kick in the leg and we deserved it. But maybe we'll learn something from it.' Kennedy's approval ratings climbed afterwards, helped in part by the vocal support given to him by Nixon and Eisenhower. Outside the United States, however, the operation undermined Kennedy's reputation as a world leader, and raised tensions with the Soviet Union.
