A former top aide to California’s Gavin Newsom was arrested and indicted on federal corruption charges this week. Dana Williamson is accused of helping in a scheme to steal campaign money from former federal Health Secretary Xavier Becerra, filling fraudulent tax forms for personal expenses and making false statements to law enforcement. Becerra is not implicated, calling the news “a gut punch.” Newsom’s office said Williamson was placed on leave “as soon as” she notified the office of the federal investigation last year. Williamson's attorney said federal authorities asked her to cooperate in a probe into the governor more than a year ago.
