Leaders of CalOptima – Orange County’s health plan for the poor – have finished an investigation into former OC Supervisor Andrew Do, who’s in prison after pleading guilty to accepting bribes and rerouting millions of tax dollars in contracts.

Do, who began his five-year prison sentence last month, sat on the CalOptima board for years during his tenure as county supervisor before he resigned from the CalOptima board in 2023 after being fined by state officials for alleged pay to play politics.

But CalOptima board members haven’t decided if members of the public will get to see the internal corruption probe, or disclose if Do’s actions impacted healthcare for the one in three county residents on the countywide insurance plan. 

“The Board is currently in the process of evaluating the information and determining next steps regarding confidentiality, privilege and the potential release of any materials,” said Janis Rizzuto, the agency’s spokesperson, in a Thursday statement. “A decision is expected by the end of the year.” 

Rizzuto did not answer questions on who conducted that investigation or what materials they had reviewed. 

The investigation was overseen by CalOptima board members Norma Garcia Guillen, Brian Helleland and Maura Byron behind closed doors. 

It’s the first completed investigation by a local agency into Do’s actions after his house was raided by the FBI in August 2024, followed by his resignation from the board of supervisors a few months later. 

All of Do’s criminal charges focused on his work as a county supervisor, where prosecutors said he accepted over $800,000 of bribes in exchange for redirecting at least $12 million in contracts to other contractors. 

Orange County Supervisor Don Wagner called on CalOptima board members to release the study, noting “more disclosure is better than less.” 

“If you don’t have anything to hide, don’t look like you’re hiding something,” Wagner said in a Friday interview. “I’m glad they’ve done it, I don’t know what they’ve found. If it’s anything major, let’s make it public.”

Before Do faced criminal charges, his conduct at CalOptima led to a state audit and his resignation from the board in 2023. 

State auditors found that under Do’s chairmanship on the board, CalOptima had inappropriately appointed multiple executives and boosted its CEO’s compensation to over $840,000.

Do also pitched having county supervisors take over as the exclusive overseers of CalOptima, but the proposal was shot down due to a change in state law. 

Meanwhile, CalOptima leaders have continued to stockpile funds after Do’s departure, now sitting on over $1.8 billion in reserves after state auditors urged them to spend more on patient care.

CalOptima board members are next scheduled to meet on October 2.
