Thousands gathered at Arlington National Cemetery on Wednesday (June 6th) to honor the 50th anniversary of Robert F. Kennedy’s death at the hands of Sirhan Sirhan during his 1968 presidential campaign.

In an ABC News report, Speakers remembered the fallen politician by reading excerpts from his speeches, including civil rights leader Rep. John Lewis, who read from Kennedy’s speech after Martin Luther King Jr. assignation, and Parkland school shooting survivor and activist Emma Gonzalez, who read a speech Kennedy gave in apartheid South Africa.
