President-elect Joe Biden turns 78 today, and when he is sworn in as president in January, he will be the oldest person in US history to have the job.
He will beat, by eight years, the record set by President Trump when he was elected in 2016 at age 70.
Biden was among the youngest men ever elected to the Senate in 1972, and in his third bid for the presidency, his life story of overcoming personal tragedy met the moment of a nation in the grips of health and economic crises.
Vice-president elect Kamala Harris will also be making history when she takes office. She will become America's first female, first Black and first South Asian vice president.
