On July 13, 1960 at the Democratic National Convention in Los Angeles, John F. Kennedy was nominated for president. Kennedy Onassis did not go to the convention because of her pregnancy. She was in Hyannis Port where she watched the September 26, 1960 debate, which was the nation's first televised presidential debate, between her husband and Republican candidate and Vice President Richard Nixon. Her husband would go on to be elected the 35th President of the United States, after winning the presidential election by a narrow margin in November. A little over two weeks after the election, on November 25, Kennedy Onassis gave birth to the couple's first son, John F. Kennedy, Jr.
