BOSTON (AP) - Rep. Patrick Kennedy says people are entitled to believe his father went unpunished for the death of Mary Jo Kopechne (co-PECK'-nee), but the late senator went on to save millions through his health care, AIDS prevention and other works.
The Rhode Island Democrat also told NBC's "Today" show on Monday his father's battle with brain cancer and writing his memoirs let him to open up more emotionally than ever before.
The senator's other son, Edward Kennedy Jr., told ABC's "Good Morning America" the family was always concerned his father could be assassinated like his brothers, President John F. Kennedy and Sen. Robert Kennedy.
He recalls seeing a bulletproof vest hanging in a closet as his father considered running for president in 1984.
Kennedy's memoirs, "True Compass," hit bookstore shelves Monday.
