The sheriff had previously kept matters related to her removal private until her legal team made confidential documents public.
SAN MATEO COUNTY, CA — The San Mateo County Sheriff, who is currently facing removal by the board of supervisors, has now asked for the upcoming proceedings to be made public and said she had restrained from responding out of respect for employee privacy.
“This proceeding is not just about me,” Sheriff Christina Corpus said. “It’s about exposing the deeply rooted double standards and inequities that persist in our county government, where power, influence, and political alliances too often overshadow fairness, due process, and accountability.”
Measure A, valid until Dec. 31, 2028, allows the Board to remove a sheriff with a four-fifths vote for cause, including violating laws, neglecting duties, misappropriating funds, falsifying documents, or obstructing investigations.
“No more one-sided narratives, or deceiving the residents of this county,” Corpus said. “Let the public see the facts. Let them hear the truth. Let justice pierce the veil of corruption and bring light where darkness has reigned for far too long.”
Corpus faces allegations of conflict of interest and retaliation against staff, detailed in court documents and a public report.
The "Keker Report," used by the San Mateo County Board of Supervisors to justify their decision to remove her, claims Corpus violated conflict of interest laws, neglected duties, and retaliated against perceived threats. Corpus denies these allegations and is appealing her removal.
The previously sealed Keker Report was made public when Corpus' lawyers filed a petition on June 27 for a restraining order against the Board of Supervisors to stop removal proceedings.
Hundreds of pages of documents were released, including the intent to remove the sheriff, the Keker Report, a transcript of the pre-removal conference, and a recommendation for removal.
Corpus’ lawyers submitted these documents to the court unsealed, making them publicly available on the Superior Court’s website without the County's involvement, confirmed Effie Milionis Verducci, interim director of strategic communications for San Mateo County Executive’s Office.
The Keker report alleges that after taking office, Corpus created an unposted "Executive Director of Administration" role, hiring a man with whom she allegedly had an inappropriately close, concealed relationship.
Corpus's lawyer, Thomas Mazzucco, denied these allegations, stating they were "rife with hearsay, gossip, and rumors."
The Keker report details Sheriff Corpus's retaliation against the Deputy Sheriff's Association president. In June, Corpus denied political motivation, claiming the DA's office confirmed probable cause, according to the report.
In a previously unreleased June pre-removal hearing transcript, Corpus denied claims against her, asserting retaliation for not aligning with former Sheriff Carlos Bolanos's administration.
Corpus has appealed to the board of supervisors, triggering a review hearing within 30 to 60 days.
The sheriff’s legal team has not responded for comment on the Keker Report.
"The people of San Mateo County deserve to hear the truth directly, not filtered through political agendas, biased narratives, erroneous reports, or closeddoor deliberations," Corpus said.
