The charges stem from a multiyear investigation led jointly by the FBI and IRS Criminal Investigation.
The indictment, unsealed by the U.S. Attorney’s Office for the Eastern District of California, outlines what prosecutors describe as a sustained pattern of financial misconduct that occurred between February 2022 and September 2024 — a period that almost entirely overlaps with Williamson’s tenure as Governor Newsom’s chief of staff.
Alleged Misuse of Political Campaign Funds
At the center of the case is an alleged scheme to improperly access and repurpose approximately $225,000 from a dormant political campaign account.
According to prosecutors, Williamson and an associate conspired to move the funds through multiple business entities they controlled, disguising the transfers as payment for a job that, in reality, required no work.
Federal authorities say the purpose of the arrangement was to make the political funds appear to be legitimate business income while obscuring their political origin.
The indictment alleges that no actual services were performed in exchange for the payments, a tactic prosecutors characterize as a “no-show job” scheme.
By routing the funds through business accounts rather than transferring them directly, investigators allege Williamson sought to avoid scrutiny from regulators and financial institutions, as well as from campaign finance authorities.
A Powerful Role Inside California Government
Williamson served as Governor Newsom’s chief of staff from 2022 until the end of 2024, a role that gave her sweeping authority over policy coordination, staffing, scheduling, and strategic decision-making inside the governor’s office.
As chief of staff, she was widely regarded as one of the most powerful figures in California politics who did not hold elected office.
Before joining the Newsom administration, Williamson held senior positions under former Governor Jerry Brown, including roles as a top advisor and cabinet secretary.
Her long résumé in Democratic politics made her a well-known figure within California’s political establishment.

Broad Range of Federal Charges
The federal grand jury returned an indictment charging Williamson with an extensive list of alleged offenses, reflecting what prosecutors say is a broad and deliberate pattern of misconduct rather than an isolated lapse in judgment.
The charges include:
Conspiracy to commit bank fraud and wire fraud
Bank fraud
Conspiracy to defraud the United States
Obstruction of justice
Subscribing to false tax returns
Making false statements to federal investigators
According to the Sacramento Bee, which first reported details of the indictment, there are 23 total counts. Of those, 18 bank and wire fraud charges each carry a statutory maximum penalty of 20 years in federal prison and fines of up to $250,000 per count.
The tax-related charge carries a potential maximum fine of $100,000, in addition to possible imprisonment.
Williamson was indicted alongside several co-defendants, including Greg Campbell and Sean McCluskie, as well as two additional individuals named in the charging documents.
