Rep. Darrell Issa, R-Calif., announced Friday that he will retire at the end of his current term, closing out a quarter-century career in Congress. He simultaneously threw his endorsement behind San Diego County Supervisor Jim Desmond to succeed him in California's newly redrawn 48th District.

Issa confirmed the decision to Fox News, calling Desmond a "true patriot" and framing the transition as a deliberate passing of the torch rather than a forced exit.

"Jim is not only a personal friend, he's a true patriot, a Navy veteran, a successful businessman and has a 20-year record of public service. He understands this community, was born and raised here and will make a terrific Congressman."

The retirement caps a career that spanned 25 years on Capitol Hill and another 25 in the private sector before that. Issa made clear this was a choice, not a concession. He pointed to strong polling and support from President Trump as evidence that he could have won reelection.

"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 Issa said the time had come for something new.

"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."

A Career-Defining Mission, Finally Accomplished

Issa singled out one accomplishment above the rest: securing the Congressional Medal of Honor for retired Navy Capt. Royce Williams. It was a fight that consumed a decade and met rejection after rejection.

"For a decade, my team and I waged a nonstop fight for Royce, and we were turned down on his behalf more times than I can remember."

That changed this year. Issa credited President Trump with making the award possible and described the moment the first lady placed the Medal of Honor on Williams as more than a legislative victory.

"President Trump made Royce's award possible, and when I witnessed the first lady place the Medal of Honor on my hero, it was more than just a job done. It felt like a career accomplishment."

There are worse notes to go out on than watching a hero finally receive what he earned.

The District Gets Redrawn, the Fight Continues

Issa's seat sits in California's 48th District, which has been redrawn under the state's Prop 50 to favor Democrats. That redistricting backdrop makes the succession fight consequential. A safe Republican seat this is not, at least not anymore.

NRCC Spokesman Christian Martinez praised Issa's tenure and signaled confidence that the seat would stay red, while sharpening the contrast with the likely opposition.

Martinez described progressive Marni von Wilpert and socialist Ammar Campa-Najjar as representatives of the "radical agenda and chaos" that voters in the district would reject.

"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."

The NRCC's framing is instructive. In a district redrawn to tilt left, Republicans aren't retreating. They're choosing their ground and their candidate early.

Desmond, a Navy veteran with two decades in public service, fits the profile of a candidate built for a competitive district: military credentials, local roots, and a record in elected office. Issa's early and emphatic endorsement is designed to clear the field before it gets crowded.

Issa's Parting Shot at Congress Itself

In a phone interview, Issa offered a blunt assessment of the institution he is leaving. He argued that Congress has "diminished itself," driven by the toxic combination of outside money and social media posturing.

"They have really, unfortunately, allowed outside money to exceed inside money in elections. And more people live and die with social media rather than substance, so, I'm hoping that there's a pendulum there. You know, some of only Congress can change."

It's a familiar lament from departing members, but Issa isn't wrong. The incentive structure in Washington rewards performance over policy, clips over legislation.

Members build brands on platforms designed to reward outrage, not outcomes. The question is whether anything short of structural reform can reverse that drift, and whether anyone still serving has the appetite to try.

Issa pledged to remain fully engaged through 2026.

"There is still work to be done throughout 2026 both in Washington and my beloved current 48th District. And as many days that remain, I'll dedicate each one of them to the people I serve and the indispensable nation I have sworn to protect as a soldier in the Army and as a proud and grateful Member of the People's House of Representatives."

Twenty-five years in Congress. Twenty-five in business before that. A decade-long fight to honor a Navy hero. Darrell Issa leaves on his own terms, with his boots still on. Now it falls to Jim Desmond to hold the line in a district California's political class is trying to flip out from under the voters who built it.
