Democrat Joe Biden won the presidency after a bitterly fought campaign in 2020 marred by the Capitol riot that followed its conclusion and is now officially gunning for a second term.
Mr Biden, 80, is no stranger to public office. He was first elected to the US Senate in 1972 and has been in Washington almost ever since, leaving public office only for a brief period between the expiration of Barack Obama’s second term as president and the beginning of his own first term.
