when does mitch mcconnell leave office

Mitch McConnell’s current U.S. Senate term runs until January 3, 2027, and he has announced that he will retire at the end of that term and not run for re‑election in 2026.

That means, barring an early resignation or unexpected change, he is expected to leave office in early January 2027, after the 2026 elections are certified and the next Senate term begins.
