SACRAMENTO — Current and former members of Gov. Gavin Newsom’s administration were among the dozens of Sacramento insiders who received FBI letters in recent days notifying them that their phone calls, texts or other electronic communications had been intercepted as part of the federal corruption case tied to Dana Williamson and two other longtime Democratic operatives.
The notifications are routine in wiretap investigations once surveillance ends, but the letters set off a wave of panic across California’s political power structure. The letters are signed by Sacramento Field Office Special Agent in Charge Siddhartha Patel and began arriving in mailboxes from Sacramento to Washington, D.C., last week, according to copies of the communications shared with The Times.
The legal notifications, under the terms of the 1968 Federal Wiretap Act, are sent out routinely to people whose private communications have been captured on federal wiretaps.
A Newsom spokesperson said the governor’s office is aware that a limited number of the letters were sent to current and former members of the administration. The spokesperson said that the letters were expected given federal law requires parties to be notified. Newsom’s office said the governor did not receive a letter.
Newsom’s office said the governor is not involved in the case against Williamson. None of the charging documents released in the cases against the three aides mention Newsom.
Copies of the letters, which were provided to The Times by individuals who asked to remain anonymous, indicate the period of time the communications were intercepted ranged from May 2024 to the end of July of 2024.
“This letter does not necessarily mean you were the target of the investigation or that any criminal action will be taken against you,” Patel wrote in the letter. “Rather, the purpose of this letter is to notify you that some of your communications may have been intercepted during the course of the investigation.”
Williamson, known as one of California’s toughest political insiders who previously worked as chief of staff to Newsom, was arrested last week on federal charges that allege she siphoned $225,000 out of 2026 gubernatorial hopeful Xavier Becerra’s dormant state campaign account. She also was accused of spending $1 million on luxury handbags and high-flying travel and illegally declaring them as business expenses on her tax returns.
According to the 23-count indictment, Williamson conspired with Becerra’s former chief deputy in the California attorney general’s office and ex-chief of staff Sean McCluskie, along with lobbyist Greg Campbell to bill Becerra’s dormant campaign account for bogus consulting services.
Williamson has pleaded not guilty to the charges.
The highly publicized indictment against Williamson was sprinkled with references to her phone calls and text messages, indicating that federal investigators were likely relying on wiretapping. But the letters informing a wide swath of political insiders, from lobbyists to other operatives, is causing widespread anxiety across the Capitol.
The exact number of letters sent by the FBI is unknown, but political insiders say they’ve heard dozens of people have received one.
“It sends a chill up your spine, and everybody is worried,” said Democratic consultant Steve Maviglio, who said he did not receive a letter. “They can’t remember what they said to whom, about what. It could be anything. I think most people think this could be the tip of the iceberg. They are very concerned about where all these roads might lead.”
