The discovery of a second set of potentially mishandled documents has cast a shadow over an otherwise bright spell for Joe Biden's presidency, including a rebound in his approval ratings, ahead of a likely decision and announcement on a re-election bid in 2024.⁠ ⁠ ⁠ On Thursday, the US attorney-general appointed a special counsel to investigate the matter.⁠ ⁠ The revelations will make it more complicated for Biden and congressional Democrats to criticise former president Donald Trump for his mishandling of sensitive government records at his Mar-a-Lago estate in south Florida.⁠ ⁠ Image: Andrew Caballero-Reynolds/AFP
