Title: John F. Kennedy
Content:  The Kennedy family is one of the most established political families in the United States, having produced a president, three senators, three ambassadors, and multiple other representatives and politicians, both at the federal and state level. While a Congressman, Kennedy embarked on a seven-week trip to India, Japan, Vietnam, and Israel in 1951, at which point he became close with his then 25-year-old brother Bobby, as well as his 27-year-old sister Pat. Because they were several years apart in age, the brothers had previously seen little of each other. This 25000 mi trip was the first extended time they had spent together and resulted in their becoming best friends. Bobby would eventually play a major role in his brother's career, serving as his brother's attorney general and presidential advisor. Bobby would later run for president in 1968 before his assassination, while another Kennedy brother, Ted, ran for president in 1980.

Kennedy, who followed the path first planned for his brother by advancing from the House to the US Senate and then to the presidency.
