SACRAMENTO, Calif. (AP) — California Gov. Gavin Newsom said Monday that federal authorities have recently contacted individuals connected to him and his wife, Jennifer Siebel Newsom, describing the activity as an attempt to target a political opponent.

Newsom said investigators have reached out to former aides and others associated with organizations linked to his wife. He suggested the inquiries are tied to his national political profile and potential future ambitions.

People familiar with the matter told several media outlets that federal investigators are reviewing issues involving entities connected to the Newsoms, though the exact nature and scope of the inquiries have not been publicly disclosed. Those sources disputed claims that the matter was initiated for political reasons.

The Justice Department and FBI declined to comment. No charges have been announced, and neither Newsom nor his wife has been accused of wrongdoing.

The reported inquiries come amid an increasingly public feud between Newsom and President Donald Trump over a range of political and policy issues.
