What we know about the Justice Department investigation into Jennifer Siebel Newsom

Key Points:

• The Justice Department is investigating Jennifer Siebel Newsom, wife of California Gov. Gavin Newsom, for tax-related conduct, with the probe involving interviews and grand jury subpoenas, according to sources familiar with the case.
• The investigation was initiated last year by the U.S. Attorney’s Office in Sacramento based on whistleblower reports, and DOJ leadership in Washington, D.C., is reportedly not involved in launching the probe.
• Gov. Newsom has publicly condemned the investigation as politically motivated retaliation by former President Donald Trump, accusing the administration of targeting him due to his criticism of Trump and potential 2028 presidential ambitions.
• The probe into Siebel Newsom is separate from other investigations involving Newsom associates, including the indictment and guilty plea of former chief of staff Dana Williamson on fraud-related charges.
• Acting Attorney General Todd Blanche, nominated to lead the DOJ permanently, has declined to comment on the investigation amid his Senate confirmation process, which faces increased scrutiny due to the probe.
