What happens if Mitch McConnell is unable to finish his US Senate term?

Republican Senator Mitch McConnell, 84, was hospitalized after a fall on June 14, leaving him briefly unconscious. After weeks of silence, he confirmed he is recovering, but his frail health reignites questions about succession if he cannot finish his term, which ends in January. McConnell is not seeking re-election, and Republicans aim to preserve their Senate majority, especially after the sudden death of Lindsey Graham.
