Emergency dispatch audio made public Wednesday indicates that Sen. Mitch McConnell, R-Ky., suffered cardiac arrest during the medical emergency that sent him to a Washington hospital last month, providing new details about an incident that had previously been described only in general terms by his office.

The dispatch audio relates to a June 14 emergency response at McConnell's home in Washington, D.C.

According to the recording, firefighters and paramedics were dispatched to the residence at 8:43 a.m. for a report of an unconscious person. After arriving, first responders radioed that McConnell was in cardiac arrest as they began emergency treatment.

Journalist Desiree Townsend first reported the contents of the dispatch audio.

McConnell's office did not immediately comment Wednesday on the newly disclosed details.

At the time of the incident, the senator's office said only that he had been hospitalized and was receiving medical care, without disclosing the nature of the emergency. A day later, aides said McConnell was recovering and continuing to work remotely on Senate business.

The newly released audio marks the first public indication that McConnell's condition was significantly more serious than previously known.

The 84-year-old Republican has faced several health challenges in recent years. In 2023, he sustained a concussion and fractured ribs after falling at a Washington hotel.

Later that year, he twice froze during separate public appearances, episodes that his office attributed to lightheadedness following a concussion. Earlier this year, he was hospitalized after experiencing what aides described as flu-like symptoms.

McConnell stepped down as Senate Republican leader at the start of the 119th Congress after serving a record 18 years in the position. He announced earlier this year that he will not seek reelection in 2026, bringing to a close a Senate career that began when he was first elected in 1984 and took office the following year.
