Calderon's State Senate district represented around 70% of the redrawn thirty-eighth.  Calderon quickly withdrew from the race in January 2012. 
On June 4, 2013, the Federal Bureau of Investigations raided Calderon's offices in the California State Capitol in an attempt to find evidence regarding accusations of criminal activity.  On the same day, the FBI also raided the office of California's Latino Legislative Caucus of which Calderon is vice chair. On October 30, 2013, an FBI affidavit was published online by by cable news network Al Jazeera America with a claim that State Sen. Ron Calderon accepted about $88,000 in bribes from an undercover FBI agent posing as a film studio owner and a Southern California hospital executive, during a wide-ranging probe into his conduct as a legislator.  On November 12, 2013, Calderon was suspended from his committee assignments, citing the ongoing inquiry into the alleged bribe.
