Daily SumUp

Former US President Joe Biden struggled to recall key milestones from his own life during an interview two years ago with a justice department investigator, according to audio.

A recording obtained by political outlet Axios shows the Democrat appeared to have trouble remembering the year he left office as vice-president, or the date of his son Beau's death.

White House aides at the time denied the president had such memory lapses. Biden was questioned by Special Counsel Robert Hur's team about why he had kept classified documents at his home and former office.

The prosecutor ultimately decided not to charge the president despite finding he had retained classified material.
