LOS ANGELES (CNS) - State Sen. Ron Calderon and his brother were  indicted by a federal grand jury on multiple political corruption charges,  including mail and wire fraud, bribery and money laundering, the U.S.  Attorney's Office announced today.

Calderon, D-Montebello, and his brother Tom were named in a federal  indictment filed Thursday. Federal investigators were expected to provide  details of the charges at a midday news conference in downtown Los Angeles.

According to the indictment, the lawmaker ``would solicit and accept  benefits, such as employment for his son, trips on privately charted airplanes,  golf at exclusive, high-end golf resorts and meals at expensive restaurants''  from Michael D. Drobot, the chief executive officer of Pacific Hospital of Long  Beach.

The alleged bribes were offered in exchange for the senator's support of  legislation that would delay or limit changes in California's workers'  compensation laws, according to the indictment.

The lawmaker is also alleged to have taken bribes from an undercover FBI  agent and a businessman in a separate scheme to affect legislation to extend  film-industry tax credits.

Defense attorney Mark Geragos said previously there was no justification  for the probe.

Ron Calderon was elected to the state Senate in 2006. His district  includes Bell, Bell Gardens, Cudahy, Montebello and Whittier, along with other  cities.

Born and raised in Montebello, Calderon worked in the manufacturing  industry and as a mortgage banker and real estate agent before he was elected.
