HONOLULU (HawaiiNewsNow) – Cabinet member Ryan Yamane abruptly stepped down as director of the Department of Human Services Tuesday.

Multiple sources tell HNN Investigates the announcement came just days after Yamane was called in to testify in the criminal bribery case.

The attorney general’s special investigation team is apparently looking into the state’s COVID testing contracts.

“This may be the beginning of a much larger story,” said HNN political analyst Colin Moore. “Are there going to be more lawmakers involved? Is this the tip of the iceberg?”

Yamane’s role in state government

Yamane was appointed director of DHS by Gov. Josh Green in 2024, putting him in charge of one of the largest state departments with 2,400 positions and a budget of more than $4 billion.

Before that, Yamane spent 20 years in the House and it was his time as chair of the House Health Committee during COVID that has him wrapped up in the bribery investigation.

“It became one of the most important committees because they were managing the legislation and the projects around protecting folks during COVID. All of the testing sites were being set up. They were beginning to roll out the vaccines. They had tremendous power,” Moore said.

In his retirement letter to DHS employees, Yamane said his retirement was effective the same day. It took many by surprise.

HNN Investigates reached out to Yamane for comment but did not receive a response.

Office of the Governor communications director Makana McClellan said in a statement: “We thank him for his 22-plus years of service to his constituents as a legislator and to our residents who rely on DHS services. Ryan will be succeeded by current Deputy Director Joseph H. Campos II, who will serve as acting director.”

Broader investigation

Multiple Department of Health employees also recently received subpoenas to testify.

A subpoena is a legal order requiring a person to testify. The Attorney General has said dozens of subpoenas have gone out.

A subpoena is not the same as a target letter, which notifies a person that criminal charges are likely ahead.

Three target letters have gone out as part of the investigation. Lt. Gov. Sylvia Luke took a leave of absence after she received one.

Below is Yamane’s retirement announcement letter that was sent to thousands of DHS employees Tuesday:

Aloha DHS Ohana,

After much reflection and with heartfelt gratitude, I am writing to formally announce my retirement effective May 19, 2026.

Serving as Director has been one of the greatest honors of my professional career. I am deeply grateful for the dedication, compassion, and professionalism each of you brings to our department every day. Together, we have worked to support our keiki and the most vulnerable in our community to make a meaningful difference in the lives of those we serve.

I want to sincerely thank all staff members for your collaboration, commitment, and support throughout my tenure. The accomplishments we achieved were only possible because of your hard work and unwavering dedication.

Thank you again for allowing me the opportunity to serve alongside you. I wish you all continued success, fulfillment, and happiness both professionally and personally.
