Speakers including House Minority Leader Nancy Pelosi and Parkland school shooting survivor Emma Gonzalez read quotes from Kennedy speeches to the crowd, which included Kennedy's widow, Ethel.

Country singer Kenny Chesney sang "This Land Is Your Land."

Robert Kennedy, a 1968 presidential candidate, was shot and killed after winning the California primary in June 1968. He was 42.

A special exhibition is also planned at the home in suburban Boston where Kennedy was born.
