A California state Senate official says the FBI raided a senator's two offices but did not search the office of the 23-member Latino caucus.
Agents spent more than six hours Tuesday searching the main office of Sen. Ron Calderon, a Democrat from the Los Angeles area.
The Senate's chief sergeant-at-arms, Tony Beard, said Wednesday agents also searched a separate office assigned to Calderon in the Legislative Office Building across the street from the Capitol.
Beard previously said the second site was home to the Latino caucus. He clarified Wednesday that the Latino caucus moved into new offices earlier this year.
The FBI isn't giving details on the investigation, which originated in Southern California.
