Federal prosecutors slapped Dana Williamson, California Governor Gavin Newsom’s former chief of staff, with public corruption charges Wednesday, according to a federal indictment.

Williamson, who exited the governor’s office in December 2024, is accused alongside political insiders Greg Campbell and Sean McCluskie of conspiring to commit wire and bank fraud. The feds say the crew faces 23 counts in total — 18 of which each carry a possible 20-year prison term and up to $250,000 in fines.

She’s expected to appear in federal court in Sacramento on Wednesday afternoon. Williamson did not respond to a request for comment. McCluskie and Campbell couldn’t be reached, and it wasn’t clear whether any had secured legal counsel.

Prosecutors allege Williamson kept her fingerprints on the scheme even after joining Newsom’s administration — transferring control to another co-conspirator but staying involved behind the scenes.

“Ms. Williamson no longer serves in this administration,” a spokesperson said. “While we are still learning details of the allegations, the Governor expects all public servants to uphold the highest standards of integrity. At a time when the President is openly calling for his Attorney General to investigate his political enemies, it is especially important to honor the American principle of being innocent until proven guilty in a court of law by a jury of one’s peers,” his office said.

McCluskie, a longtime aide to former California Attorney General Xavier Becerra — now running for governor — is also implicated. Between February 2022 and September 2024, prosecutors say Williamson and her co-conspirators siphoned roughly $225,000 from Becerra’s dormant campaign account to line McCluskie’s pockets.
