Federal officials raided Democratic Sen. Leland Yee's office at the Capitol on Wednesday, carting away at least nine packages of possible evidence.
Yee was arrested as the FBI said it was executing multiple search warrants and "conducting arrests in multiple locations today." Multiple Bay Area media reports have said he is scheduled to be arraigned at 1:30 p.m. in San Francisco.
In Sacramento, Senate Sergeant-at-Arms Tony Beard told reporters that the officials arrived at Yee's fourth-floor office at the Capitol about 7 a.m. The officials, including representatives from the FBI, were seen leaving just before noon.
On their way out, Beard requested that photographers refrain from shooting their faces.
