Richard Pavlick is arrested for plotting to assassinate U.S. President-Elect John F. Kennedy.

Richard Paul Pavlick was a retired postal worker from New Hampshire who stalked Senator and U.S. president-elect John F. Kennedy, with the intent of assassinating him. On December 11, 1960, in Palm Beach, Florida, Pavlick positioned himself to carry out the assassination by blowing up Kennedy and himself with dynamite, but delayed the attempt because Kennedy was with his wife Jacqueline and their two young children. He was arrested before he was able to stage another attempt.

The president-elect of the United States is the candidate who has presumptively won the United States presidential election and is awaiting inauguration to become the president. There is no explicit indication in the U.S. Constitution as to when that person actually becomes president-elect, although the Twentieth Amendment uses the term "president-elect", thereby giving the term constitutional basis. It is assumed the Congressional certification of votes cast by the Electoral College of the United States – occurring after the third day of January following the swearing-in of the new Congress, per provisions of the Twelfth Amendment – unambiguously confirms the successful candidate as the official "president-elect" under the U.S. Constitution. As an unofficial term, president-elect has been used by the media since at least the latter half of the 19th century and was in use by politicians since at least the 1790s. Politicians and the media have applied the term to the projected winner, even on election night, and very few who turned out to lose have been referred to as such.

John Fitzgerald Kennedy, also known as JFK, was the 35th president of the United States, serving from 1961 until his assassination in 1963. He was the first Roman Catholic and youngest person elected president at 43 years. Kennedy served at the height of the Cold War, and the majority of his foreign policy concerned relations with the Soviet Union and Cuba. A member of the Democratic Party, Kennedy represented Massachusetts in both houses of the United States Congress prior to his presidency.
