Kentucky Senator Mitch McConnell remains hospitalized following his admission on June 14 for unspecified health issues. The 84-year-old lawmaker, who is set to retire in January, has not had any public updates regarding his condition, prompting speculation about his ability to return to the Senate when it reconvenes next week after a two-week recess.

In recent days, the Senate’s top two Republicans have reached out to McConnell individually. Senate Majority Leader John Thune, a Republican from South Dakota, spoke with McConnell by phone on Monday, according to a spokesperson. The following day, Senator John Barrasso of Wyoming, the Senate Republican Conference’s second-ranking member, had a 20-minute conversation with McConnell, his office confirmed.

McConnell’s aides have declined to provide further details on his health, maintaining a level of privacy that has left colleagues and observers uncertain about his current status and readiness to resume his Senate duties.
