Peevey stepped down from the CPUC late last year. The former president is under fire for alleged backdoor dealings with PG&E in the wake of the 2010 San Bruno pipeline explosion that killed eight people.

Earlier this year, investigators filed a search warrant and seized a list of items form Peevey’s Southern California home, including computers, a thumb drive, notes and six years worth of day planners.

Investigators are also looking into a meeting involving Peevey and an executive with Southern California Edison in 2013 about problems at the San Onofre nuclear power plant. They were required to tell the public about their talk, but the meeting was not revealed until this week.
