 In late June, more than a dozen FBI agents streamed out of Oakland Mayor Sheng Tao's home. They confirmed they were conducting court-authorized law enforcement activity, but provided no more details. The house was one of at least two locations the FBI said they raided that day. The other was connected to the Duong family, which runs California Waste Solutions, the city's recycling service. In a statement, a spokesperson for the company said the family's homes had also been raided.
