Donald Trump has been photographed in the Oval Office clutching a printed briefing card that closely resembles materials once used by his supporters to question Joe Biden's mental fitness, prompting fresh allegations of double standards from critics.
The photograph, taken on Monday, showed Mr Trump hosting a 16-year-old Californian lifeguard and the 10-year-old boy she had rescued. In his hand was what appeared to be a staff-prepared card featuring photographs of the two guests alongside scheduling notes and brief instructions for the ceremony.
