Donald Trump's struggle to walk a short corridor on Capitol Hill on Wednesday 24 June, pausing to catch his breath as TV cameras rolled and bristling at a reporter he plainly dislikes, has reignited questions about the 80-year-old president's health and fitness for office.
After years of carefully stage-managed appearances in which Trump and the White House have insisted he is in 'excellent health,' buttressed by glowing medical reports and on-camera endorsements from government doctors. That narrative is increasingly hard to square with what viewers can now see and hear for themselves. Each new clip of Trump walking slowly, gripping railings or audibly labouring through sentences is seized upon, replayed and dissected online, where his critics argue the image of boundless stamina has long since frayed.
