Republican Sen. John Curtis is calling for an investigation into Donald Trump Jr. after a report says a Russian oligarch close to President Vladimir Putin bankrolled parts of his wedding party. Multiple outlets describe Curtis’s request as seeking scrutiny of Trump Jr.’s foreign connections and potential financial or business ties linked to the event.

Curtis says similar standards should apply to both Republican and Democratic presidential families. Several sources also report that he frames his push as extending the scrutiny used in investigations involving Hunter Biden, arguing that Congress should not apply “trust us” differently depending on party.

Outlets emphasize different aspects of the proposal. Forbes and The Independent focus on Curtis’s call for a probe tied to the wedding’s funding and Trump Jr.’s response, noting that Trump Jr. and his wife defend their relationship with the oligarch. The New Republic adds detail on Curtis’s account of the matter, including a three-page letter sent to Senate Judiciary leaders and language comparing the response to earlier Biden-related inquiries. Other outlets largely summarize the call for a probe without adding extensive new factual detail.
