John F. Kennedy was the 35th president of the United States.
World War II
The Invaders were in Boston when they uncovered a plot by the rogue android Adam II to replace world leaders with android doubles. In the effort to rescue a young Senatorial candidate, John F. Kennedy, the mission succeeded but Captain America (William Naslund) lost his life.
In 1960, Kennedy became President and appointed his brother Bobby Kennedy Attorney General. The choice was controversial, with publications such as The New Republic calling him inexperienced and unqualified. However the committee voted almost unanimously for him; receiving all but one vote. President Eisenhower pardoned Isaiah Bradley on the day of Kennedy's inauguration.
In 1962, Blue Marvel received the Presidential Medal of Freedom from JFK on the day the President asked him to retire; it had been discovered by the public that he is an African-American. As the Blue Marvel, Brashear wore a full-face helmet - but when it was damaged in a battle, his identity was revealed. A massive controversy ensued as the America of 1962 was too racist to accept a black super-man. The President reluctantly decided to ask Brashear to step back. Torn between myriad considerations, the Blue Marvel conceded.
Bay of Pigs Invasion
On October 16th, 1962, Kennedy learned the Soviet Union was installing nuclear missile sites in Cuba. The president initiated a blockade of Cuba that ultimately called Khrushchev's bluff and the missiles were removed.
On Friday, November 22nd, 1963, JFK was assassinated in Dallas, Texas by a lone gunman identified as Lee Harvey Oswald.  The exact details and the truth of the incident still remained a mystery, but James "Bucky" Barnes thinks he was one of the shooters involved.
Years later, Morgan MacNeil Hardy used a Telepathy Augmentor powered by four telepaths to recreate the decent America he had known as a boy. By changing people, places, events and memories, Hardy created a restructured reality in which President Kennedy wasn't assassinated and proved to be so popular that the American people voted in an amendment that allowed him to serve more than two terms as president. In 1969, the President introduced Captain America (whose history had been changed so that he had not entered a state of suspended animation in 1945) to Sam Wilson who was later elected to Congress. In 1980, Kennedy was elected to his sixth consecutive term as president and recruited Captain America to undertake sensitive diplomatic missions. In 1981, President Kennedy had begun to promote his plan for the unification of North and South America, and he was encouraging the public to join the movement for lunar colonization.
After learning how history had been altered, Captain America fought to reverse it and, once the Telepathy Augmentor was destroyed, the world and its history returned to what it had been, including President Kennedy's assassination in 1963.
The following appearances of John F. Kennedy should be considered topical references: When Doctor Doom threatened to wage a one-man war against the US unless he received a post in the President's Cabinet, President Kennedy rejected it. Doom then caused chaos among the country's electrical and electronic devices. The Joint Chiefs of Staff asked the Fantastic Four for help, which was provided.
Years after Kennedy's death, the Jester kidnapped a technician to make him create fake footage he broadcasted as real, including images suggesting that President Kennedy and his brother were still alive, hidden because of an international conspiracy, and several others (such as the fact that Vietnam War never existed and was a cover for illegal wars, and footage to ridicule D.A. Franklin Nelson before the elections) to boost the conspiracy-minded fear in the population.
