WASHINGTON (AP) -- Their fathers led the nation in the early years amid the struggle by black America for civil rights -- and both Lynda Bird Johnson Robb and Caroline Kennedy see much work still to be done.
At the 50th anniversary ceremony of the March on Washington, Robb appealed for continued progress. She remembered the words of Coretta Scott King, telling the crowd that, "Freedom is never really won. You earn it and win it in every generation."
Robb's father, President Lyndon Johnson, signed the 1964 Civil Rights Act and the 1965 Voting Rights Act.
Kennedy, daughter of President John F. Kennedy and the nominee to be ambassador to Japan, said the country cannot forget all those who sacrificed so much when they marched for jobs and freedom 50 years ago.
