Amid the turbulent waters of an FBI investigation, Francis Zamora, the chief of communications for Oakland Mayor Sheng Thao, tendered his resignation on Monday, an official confirmation from the mayor’s office reveals. Zamora’s exit comes on the heels of an emotionally charged news conference where Mayor Thao declared her innocence after her home became the target of a federal search. “I resigned my position as Chief of Communications,” Zamora expressed, “I thank my colleagues for their professionalism and dedication. It was an honor to serve the City of Oakland beside them,” in a statement obtained by NBC Bay Area.
