FBI raids office, homes of Contra Costa Co. tax assessors as part of ongoing investigation

MARTINEZ, Calif. -- The FBI served three federal search warrants Tuesday morning at the Contra Costa County Assessor's office, as well as two residences, including that of the outgoing assessor, as part of an ongoing investigation.

Outgoing County Assessor Gus Kramer's home on West Arlington Street in Martinez was searched by the FBI, as well as a residence on Temple Drive in Pacheco.

While the investigation is ongoing, FBI spokesperson Cameron Polan said the agency is unable to provide further details.

Kramer has held the office for 32 years, which includes eight terms, and announced in March his intent to retire and not seek a ninth. Assistant County Assessor Vince Robb was endorsed by Kramer, according to his campaign website, and secured 67.7% of the vote for county assessor in the June 2 primary election, according to the latest vote count.

In 2019, Kramer was the subject of a civil grand jury accusation of "willful or corrupt misconduct" for creating a hostile and abusive work environment after female employees reported unwanted sexual remarks and racial disparagement. The case ultimately resulted in a mistrial.
