Xavier Becerra says he didn’t know that his former chief of staff and former political aide were taking money from his California campaign account and lying to the government about it. On the gubernatorial debate stage on Thursday, he played the victim. Prosecutors said he was not involved, he claimed. But his rivals in the primary — including Steve Hilton and Katie Porter — weren’t having it. In fact, they suggested, Becerra could still be indicted. Maybe even if he made the general election.
