A Russian businessman close to Putin paid hundreds of thousands of dollars toward Don Jr.'s wedding, and now even Republican senators want him questioned — bad news for the Trump family heading into the midterms.

• Umar Kremlev, head of the International Boxing Association and a Putin ally, covered a private Bahamian island, a fireworks show, and event planners for Don Jr.'s three-day wedding.
• Don Jr. is worth $300 million, which makes the foreign gift look less like generosity and more like buying access to the president.
• Trump brushed it off, saying such gifts are allowed and that his son paid the money back.
• Republican Senator John Curtis asked the Judiciary Committee to subpoena Don Jr., with Cornyn and Tillis signaling support — Tillis only after the election.
• Kremlev has his own agenda: his boxing body lost its Olympic role in 2023, and he has been lobbying Trump ahead of the 2028 Los Angeles games.

Outlook: An investigation looks likely, especially if Democrats take Congress in the midterms, though it will probably generate hearings rather than consequences.
