Republican senator Mitch McConnell, 84, has been in hospital for three weeks after a medical emergency at his Washington home on 14 June, and the lack of updates from his office has fuelled intense speculation in Washington. Some of Donald Trump's most vocal supporters are now demanding "proof of life", reflecting how the information vacuum has allowed rumours to spread. The matter carries political weight because Republicans are trying to hold on to a narrow Senate majority, making McConnell's status and possible return to work significant.

Paramedics reportedly responded to an unconscious person believed to have suffered a cardiac arrest, with CPR under way, though McConnell was not named on the call and his office has only said he is receiving "excellent care". Trump-aligned figure Laura Loomer claimed an unnamed White House source told her the senator was in a "vegetative state" or "brain dead" and would not return, and independent journalist Desirée Townsend said her sources had told her the same. Adding to the confusion, the outlet The Hill accidentally published and then deleted an obituary of McConnell, a screenshot of which circulated on X.
