WASHINGTON (AP) — Mitch McConnell, the longest-serving Senate leader in history who maintained his power in the face of dramatic convulsions in the Republican Party for almost two decades, will step down from that position in November.

McConnell, who turned 82 last week, announced his decision Wednesday in the well of the Senate, the chamber where he looked in awe from its back benches in 1985 when he arrived and where he grew increasingly comfortable in the front row seat afforded the party leaders.

“One of life’s most underappreciated talents is to know when it’s time to move on to life’s next chapter,” he said. “So I stand before you today… to say that this will be my last term as Republican leader of the Senate.”

AP AUDIO: McConnell will step down as the Senate Republican leader in November after a record run in the job.

AP Washington correspondent Sagar Meghani reports Mitch McConnell has told Senate colleagues this will be his last term as leader.

His decision punctuates a powerful ideological transition underway in the Republican Party, from Ronald Reagan’s brand of traditional conservatism and strong international alliances, to the fiery, often isolationist populism of former President Donald Trump.
