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

McConnell, who turned 82 last week, was set to announce his decision Wednesday in the well of the Senate, a place 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 in prepared remarks obtained by The Associated Press. “So I stand before you today ... to say that this will be my last term as Republican leader of the Senate.”

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 populism of former President Donald Trump.
