Nathan Fletcher is out.

The embattled supervisor vacated San Diego County’s 4th District on Monday, nearly six weeks after announcing his resignation.

Fletcher penned a public letter apologizing for “the mistake of engaging in consensual interactions with someone outside of my marriage.” But he once again denied allegations of sexual assault.

“I will be forever grateful for the opportunity to serve the 4th District and all County residents over the last four years, and will carry immense pride for the progress made and challenges confronted in that time. The ownership of these successes – particularly in the areas of behavioral health, child welfare, and juvenile justice – rightfully and completely belong to those members of our community who have demanded such changes, as well as the County workers who I know will faithfully implement them. I will always regret the circumstances of my departure, but more than anything, I will forever remain a fan of the work of our County government,” Fletcher wrote. “The mission and purpose of serving those most in need is so much greater and more enduring than any one flawed individual.”

Fletcher and the Metropolitan Transit System (MTS) are being sued by former MTS public relations specialist Grecia Figueroa. She claims she was sexually assaulted by Fletcher and then improperly fired from her job.

A special election for Fletcher’s replacement will be held in August. If no candidate garners more than 50%, a runoff will take place in November. 

So far, the race features San Diego City Councilwoman Monica Montgomery Steppe, veterans advocacy nonprofit CEO Janessa Goldbeck, and former District 4 candidate Amy Reichert, who challenged Fletcher’s re-election last year. 

The special election will cost approximately $2 million.
