March 7 (UPI) — Rep. Darrell Issa, R-Calif., announced he is retiring at the end of his term and put his support behind San Diego Supervisor Jim Desmond.

Issa issued a statement Friday on social media saying he will not be seeking re-election in this year’s midterm elections.

“This decision has been on my mind for a while and I didn’t make it lightly,” Issa wrote. “First, we built the right campaign infrastructure, support has been overwhelming — including from President Trump — and our polling was unmistakable: We would win this race. But after a quarter-century in Congress — and before that, a quarter-century in business — it”s the right time for a new chapter and new challenges.”

Issa offered his “enthusiastic endorsement” to San Diego Supervisor Jim Desmond, who filed to run for Issa’s seat on Friday.

The announcement comes after Gov. Gavin Newsom’s ballot measure to redraw state congressional districts, which passed in November, transformed Issa’s district from safely Republican to an area more friendly to Democrats.

Issa had previously been rumored to be considering a run for Congress in Texas, but he told Fox News in December that the plan would not be going forward.

“I’m thrilled to set the record straight and here’s the truth: Texas House members and residents of that state did ask if I would consider running there following Gavin Newsom’s historically corrupt gerrymander,” he said at the time. “I appreciate the opportunity, but California is my home. I told them I’m going to stay in Congress, and I don’t need to go to Texas for that.”

Anna Elsasser, spokesperson for the Democratic Congressional Campaign Committee, celebrated the news of Issa’s retirement in a statement.

“After over two decades of disastrous representation, Darrell Issa is once again running for the exits — and good riddance. Issa abandoning his voters now is the clearest sign yet that Republicans know he can’t win on his record of skyrocketing prices, gutting health care, and looking out for himself and wealthy special interests above all else,” Elsasser said. “Any Republican who tries to parachute into this race with the same extreme agenda will face the same fate.”

Christian Martinez, a spokesman for the National Republican Campaign Committee, praising Issa for his “decades of dedicated service” in a statement provided to Politico.

“We are optimistic that this district will continue to be represented by a Republican who will stand for common sense and reject the radical agenda and chaos that progressive Marni von Wilpert and socialist Ammar Campa-Najjar would bring,” Martinez said.
