OAKLAND — Alameda County prosecutors have filed criminal charges against former Coliseum Authority Executive Director Scott McKibben for allegedly violating state conflict-of-interest laws by seeking a $50,000 fee for helping negotiate a stadium naming rights deal at the home of the A’s and Raiders.

As the head of a public agency negotiating a $3 million deal with RingCentral, McKibben allegedly committed a felony by violating Government Code 1090, which prohibits public officials from having a financial interest in contracts made by them in their official capacity, according to court documents filed Nov. 27.

He also faces a misdemeanor for violating Government Code 87100: “No public official at any level … shall make, participate in making or in any way attempt to use his official position to influence a government decision in which he knows or has reason to know he has a financial interest.”

When asked to respond, McKibben texted that “neither I or my attorney have heard anything or received any notification as of today. If so, my attorney will have a comment.” He is ordered to appear in court on Jan. 10.

District Attorney Inspector Thomas P. Cleary, in court documents, wrote that the stadium authority board did not know McKibben had requested a commission fee when it approved the contract on May 31. Now, the board made up of Oakland council members and Alameda County supervisors is working to renegotiate the deal.

According to Cleary, McKibben mentioned his $50,000 fee during RingCentral executives’ first site visit at the Coliseum at the end of 2018. McKibben told them the fee would “be paid by RingCentral if the naming rights agreement was approved” by the authority board.

After the board approved the deal, RingCentral asked McKibben to send invoices. Three invoices obtained by this newspaper show McKibben sent two — on June 17 and June 20 — on Oakland-Alameda County Coliseum Authority letterhead and signed them. A third, emailed five days later and also signed by McKibben, only listed his name and home address in Pleasanton.

Once Alameda County Counsel and the Oakland City Attorney’s Office became aware of the invoices, they notified RingCentral of the conflict of interest and the fee was not paid, Cleary wrote.

McKibben resigned Aug. 9. A week later, members of County Counsel and the City Attorney’s Office contacted the Alameda County District Attorney’s Office, which opened an investigation.

McKibben admitted to requesting a $50,000 fee but “stated he believed that in his position as an Executive Director he was a consultant and could seek outside work,” Cleary wrote. “McKibben considered the naming rights negotiations outside his role as Executive Director and viewed the fee as proper, below market rate and not interfering with his negotiations on behalf of the” Coliseum stadium authority.

The criminal case comes as McKibben is preparing for the inaugural season of the Oakland Panthers, an indoor football league team that will play at the Oakland Arena. McKibben is the president of the team co-owned by Oakland native and former NFL star Marshawn Lynch and Roy Choi. Tickets go on sale Dec. 9; the first home game is March 14.

McKibben took the helm of the Coliseum authority in 2015, eventually earning $300,000 a year. He nearly left in 2017 to take a job with Levi’s Stadium in Santa Clara but stayed after Alameda County matched the salary and perks he was offered and extended his contract through 2020.

He previously worked for years as a newspaper executive, including a stint in the 1990s as president and publisher of the Alameda Newspaper Group, which operated the Oakland Tribune and other Bay Area papers at the time. He became executive director of the Tournament of Roses and the Rose Bowl Game in Pasadena in 2009, and later served as CEO of the A-11 Football League, an alternative to the NFL.

In addition to the DA’s investigation, the Coliseum authority board hired a firm to investigate McKibben’s actions as CEO and executive director. That investigation is ongoing.
