Federal scrutiny of Governor Gavin Newsom has intensified as investigators expand a criminal probe into his international travel and personal expenditures. In early September 2026, subpoenas were issued in the Eastern District of California, signed by Assistant U.S. Attorney Michael D. Anderson, seeking six years of records from the California State Protocol Foundation, a nonprofit that has funded Newsom’s overseas trips. The investigation also targets communications involving Newsom’s aides, including chief protocol officer Rebecca Prowda, who oversees the governor’s foreign travel. Newsom’s office has dismissed the probe as a vindictive “witch hunt” by the Trump administration designed to “hunt for a crime that doesn’t exist,” expressing distress over the involvement of staff and family members.

This legal pressure coincides with shifting political prospects for Newsom as he nears the end of his term. While he has actively engaged in national politics through his ‘Take it Back Tour,’ recent data from Polymarket indicates his perceived odds for a 2028 presidential run have dropped to 7%. Critics suggest that domestic challenges in California, such as gas prices and homelessness, may serve as obstacles to his national aspirations. 

On the legislative front, Newsom faces decisions regarding several bills aimed at restricting federal immigration enforcement, including the “Get the Feds Out Act,” by the September 30 deadline.
