TIMELINE: Mitch McConnell's health scares leading up to his latest hospitalization

Sen. Mitch McConnell remains hospitalized more than three weeks after being admitted on June 14, as questions continue to swirl about the longtime Kentucky Republican's condition.

McConnell's office has released few details about why the 84-year-old was hospitalized. Reports last month suggested emergency responders performed CPR after he suffered a cardiac arrest, though his office has not confirmed those accounts or disclosed the reason for his hospitalization.
