Sen. Mitch McConnell (R-Ky.) remains in the hospital, and his health is improving, according to a statement from his spokesperson.

“Senator McConnell appreciates the outpouring of support he’s receiving while he continues his recovery in the hospital,” a spokesperson said. “The Senator continues to improve and is working closely with his staff on Kentucky and Senate matters while the Senate is out of session.”

McConnell, 84 years old, was hospitalized June 14, according to an earlier statement from a spokesperson that says he was “receiving excellent care.”

McConnell’s office still hasn’t disclosed why he is hospitalized. The new statement comes after the release of an audio recording suggesting that emergency responders were called to his Washington, DC, home for an “unconscious” person the same day he was hospitalized.

In the audio, the dispatcher was heard saying the call is for a “cardiac arrest,” and a paramedic is heard saying, “CPR in progress.”

McConnell, who survived polio as a child, has had a series of health issues, including spontaneously freezing during two public appearances, falls, and earlier this year, he checked himself into a local hospital because of flu-like symptoms,

McConnell announced last year that he would not be seeking reelection. If McConnell were unable to complete his term, a 2024 state law passed by the Republican legislature would govern the succession process. Under that law, the Kentucky Democratic governor, Andy Beshear, is not allowed to select a replacement; he would be required to issue a proclamation and call for a special election.
