Rep. Paul Mitchell, a second-term Michigan Republican with a House GOP leadership position, announced Wednesday that he will not run for reelection next year, voicing frustration that “rhetoric overwhelms policy” in Washington.

Mitchell, who was among the first Republican lawmakers to criticize President Trump for his racist tweets aimed at four liberal minority congresswomen, said in an emotional floor speech that he is retiring to focus more on his family.

“A career in Washington was never my objective,” Mitchell said. “My mission has always been to simply address significant challenges this nation faces: trade, health care, immigration and infrastructure, to name just a few. However, it appears to me that rhetoric overwhelms policy, and politics consumes much of the oxygen in this city.”

Mitchell, 62, represents a conservative district north of Detroit that includes much of Macomb County. He won reelection in 2018 with more than 60 percent of the vote and became the sophomore representative to the GOP House leadership.

His planned retirement from Congress was first reported by Politico. Mitchell told the publication that he was turned off by the “vitriol” in Washington.”

“It overwhelms policy, politics becomes the norm,” he said. “Everything’s about politics. Everything’s about an election. And at some point of time, that’s not why I came here.”

Following Trump’s tweets this month aimed at the four female lawmakers known as “the Squad,” Mitchell said that “these comments are beneath leaders.”

In his floor speech, Mitchell said that he has been proud to be a member of Congress.

“But I have also begun to ask myself about making a difference for my family,” he said, choking up. “My children of all ages — the youngest just 9 — have accepted their dad traveling the country, working a demanding schedule, frequently interrupted by text messages, emails and phone calls.”
