Former President Donald Trump has suggested that President Joe Biden undergo a cognitive test, while mistakenly referring to the doctor who administered his own test. Jackson, who was the White House physician during Trump’s presidency, was misidentified as “Ronny Johnson” by Trump. The comments come amid Trump’s repeated questioning of Biden’s mental sharpness. Critics seized on the gaffe, while the Biden campaign dismissed it as a misleading video. Trump also falsely claimed Biden turned away from skydivers landing at the G7 summit.
