(Updates with lawmaker surrendering to authorities)
By Dan Whitcomb
LOS ANGELES, Feb 24 (Reuters) - A California state senator turned himself in on Monday to face charges he took bribes from a businessman and from undercover FBI agents posing as Hollywood film executives to steer legislation in their favor.
Democrat Ron Calderon, a member of a family political dynasty going back several decades in California, was taken into custody after surrendering to federal authorities mid-morning on Friday, U.S. Attorney's spokesman Thom Mrozek said.
The 56-year-old lawmaker was scheduled for an arraignment on two dozen counts of bribery, fraud, money laundering and other charges in U.S. District Court in Los Angeles later in the day. A magistrate judge was also expected to set a bail amount for Calderon.
State senate leader Darrell Steinberg, meanwhile, has called on the fellow Democrat to resign or take a leave of absence during the criminal proceedings, saying the senate would otherwise seek to suspend him.
According to a 28-page indictment, Calderon is accused of taking some $100,000 in cash bribes, along with plane trips, golf outings and jobs for his children, in exchange for influencing legislation.
The senator's brother, Tom Calderon, a former member of the California State Assembly, was also named in the indictment and charged with conspiracy and seven counts of money laundering.
Prosecutors say Ron Calderon accepted bribes from Long Beach hospital owner Michael Drobot to preserve a legislative loophole that allowed Drobot to defraud the state's healthcare system out of hundreds of millions of dollars.
Drobot has agreed to plead guilty to separate federal charges and is cooperating in the case against the Calderon brothers, prosecutors say.
Calderon is also accused of accepting money from undercover FBI agents who he thought worked for an independent Hollywood movie studio in exchange for supporting an expansion of film tax credits in California.
Both Calderons are accused of laundering the bribe money by funneling it through Tom Calderon's consulting firm, Californians for Diversity.
Tom Calderon, 59, pleaded not guilty during a brief hearing in U.S. District Court in Los Angeles on Friday, and his defense attorney, Shepard Kopp, said that he "categorically denies" the charges against him.
In June, FBI agents raided the Sacramento offices of Ron Calderon and the California legislature's Latino Caucus, where he was a member of the executive board.
In November, Calderon was removed from the board of the Latino Caucus and from his legislative committee assignments by his colleagues because of the investigation.
If convicted at trial, Ron Calderon, who also faces tax fraud charges, could face a statutory maximum of nearly 400 years in prison, although federal sentencing guidelines typically call for much less time. Tom Calderon could face a maximum of 160 years behind bars. (Reporting by Dan Whitcomb; Editing by Cynthia Johnston and Andrew Hay)
