US ⁠Senator Mitch McConnell was admitted to hospital on Sunday, his spokesman said, but there was no immediate information about why he was there or his prognosis.

McConnell, 84, was the longest-serving Senate leader in history before stepping aside from that role while finishing his final term, which ends in January.

“Senator McConnell was admitted to the hospital this morning. He is receiving excellent care,” spokesman David Popp said in a statement without elaboration. It was not immediately clear whether the Kentucky lawmaker was in Washington, his home state or elsewhere.

McConnell was hospitalised earlier this year for eight days in February for “flu-like symptoms”.

The lawmaker’s health has been a subject of scrutiny for years.

He fell and sprained his wrist while walking out of a Republican lunch in December 2024. He was hospitalised with a concussion in March 2023 and missed several weeks of work after falling in a Washington hotel. After he returned, he twice froze during news conferences that summer, staring vacantly ahead before colleagues and staff came to his aid.
