California Sen. Ron Calderon and brother, Tom Calderon, were indicted on public corruption charges Friday stemming from an investigation that ensnared other members of his powerful political family.

The U.S. Attorney’s Office announced the charges at a press conference in Los Angeles following a lengthy investigation into a massive healthcare fraud scheme and bribes to expand film tax credits.

Ron Calderon has agreed to surrender Monday on 24 counts of mail fraud, wire fraud, bribery, conspiracy to commit money laundering and money laundering. The allegations, if proven, carry a maximum of 400 years in prison.

His brother, Tom Calderon, who is a former Assemblyman, will be arraigned later Friday on charges of money laundering. The allegations against Tom Calderon’s carry a maximum sentence of 160 years.

The FBI searched two Capitol offices of Ron Calderon, a Democrat from Montebello, in June. Four months later, Al Jazeera America published a sealed search warrant detailing allegations the senator accepted thousands of dollars in bribes from an undercover FBI agent and a hospital executive.

After the affidavit was leaked, Calderon filed a lawsuit in November asking for prosecutors to be sanctioned for releasing the sealed records. Calderon alleged he was retaliated against for refusing to wear a wire to record conversations with Senate leader Darrell Steinberg, D-Sacramento, and Sen. Kevin de Leon, D-Los Angeles.

However, the U.S. Attorney’s Office said in court documents responding to the lawsuit that Calderon did wear a wire, but the documents do not name the people who were recorded. The U.S. Attorney’s Office said in the court documents that Calderon flew to Las Vegas to meet someone he believed was the owner of an independent film studio on May 4.

“The FBI agents explained to Calderon that they worked for the FBI’s Public Corruption Squad and had been investigating Calderon for quite some time,” according to the US Attorney’s Office court documents. “The FBI agents did not tell Calderon they were investigating other state senators.”

Those same court documents say the leaked affidavit was from a search warrant never executed and that a second sealed search warrant actually contained more “embarrassing” details. The US Attorney’s Office said Calderon stopped cooperating with their investigation on May 18.

The charges against Calderon come as news that fellow Sen. Rod Wright will have his own sentencing delayed by two months. Wright, D-Inglewood, was found guilty of eight felonies last month of perjury and voter fraud.
