"That's the task before us."\nBiden, nodding to the towering marble likeness of the former president next to him, said America was at a turning point similar to those the country faced during the Civil War and the civil rights movement.\n\n"Are we up to it? Will we meet the moment like our forebears have? I believe we must and I believe we will," Biden added.\nHe said unity requires Americans to connect around opportunity dignity and respect to fight hate, violence, disease and hopelessness.\n"I have never been more optimistic about America," he said.
