Before dawn on a cold November 25, 1963, Knap went to the Capitol grounds to interview people waiting to view President Kennedy's casket in the Rotunda. There he met another ex-champ, Jersey Joe Walcott. On a hot August 28, 1963, Knap joined the civil rights march from the Washington Monument to the Lincoln Memorial, where he covered Martin Luther King Jr.'s "I have a dream" speech.
