Thao has maintained her innocence and denied she is at the center of a public corruption scandal. She has largely laid low since being recalled in November.

Federal authorities on Friday morning announced details of an indictment against recalled Oakland Mayor Sheng Thao, her boyfriend, and two members of the politically influential Duong family.

The Duong Family owns Cal Waste Solutions, Oakland's recycling company, which also provides junk pick-up in San Jose, and an integrated waste management facility in their native Vietnam.
