Sen. Ron Calderon turned himself into authorities this morning and is now in custody awaiting arraignment on corruption charges this afternoon in Los Angeles.
Calderon will be arraigned sometime after 2 p.m., said Thom Mrozek, spokesman for the United States Attorney's Office, which is prosecuting the case.
Last week, a federal grand jury indicted Calderon on 24 criminal charges including bribery, money laundering and tax fraud, and indicted his brother, former Assemblyman Tom Calderon, on seven counts of money laundering and one count of conspiracy to commit money laundering.
Tom Calderon was arraigned Friday and pleaded not guilty. Authorities said Ron Calderon was traveling on Friday and agreed to turn himself in today.
