The Sacramento Bee is reporting that the FBI raided the Sacramento office of Sen. Ron Calderon, D-Montebello, and the Latino Legislative Caucus today, executing a sealed search warrant for the two locations that are related to the same investigation. 
The FBI has confirmed that the warrants do not involve “a public safety issue,” according to the Sacramento Bee.
In a statement to the media, Tony Beard, the Senate’s chief sergeant of arms, said that because the warrants are sealed per the order of the Federal Court, he has no additional information about the details of the investigation, but added that the “Senate has and will continue to fully cooperate with the agents in this matter.”
Two sources, speaking on condition of anonymity, told EGP Tuesday that the cases could be related to contracts involving a San Gabriel Valley water agency and the senator’s brother, Tom Calderon, a former state legislator. One of the sourced told EGP that several people connected with the Central Basin Water District and its contractors have over the last two to three months been “questioned by the FBI,” in what was called “a widespread corruption probe.”
Responding to EGP’s request for comment, Calderon’s office referred all questions regarding the investigation to Los Angeles Attorney Mark Geragos.
Calderon represents the 30th District and is in the final two years of his term.
Emails and phone calls seeking comment from Latino Caucus chair, Assemblyman Ricardo Lara, D-Bell Gardens, were not immediately returned.
The Latino Caucus is made up State Senate and Assembly office holders, currently all Democrats.
