Congressional subpoena request
On 22 September 2026, Republican Senator John Curtis of Utah sent a formal letter to Senate Judiciary Committee Chairman Chuck Grassley and ranking Democrat Dick Durbin. The letter requested an inquiry into whether relatives of sitting presidents use familial status for private financial gain, preferential treatment, or access by domestic and foreign interests. Curtis specifically asked the committee to issue subpoenas to both Donald Trump Jr. and Hunter Biden, the son of former president Joe Biden. The request established a public break between a sitting Republican senator and the White House. Curtis argued that congressional oversight standards must apply equally regardless of which political party holds executive power.
“The country should not have to accept one standard for the family of a Republican president and another for the family of a Democratic president.”
Bahamas festivities and Russian funding
The subpoena demand followed reporting published by ProPublica regarding Donald Trump Jr.'s wedding festivities with Bettina Anderson in the Bahamas in May 2026. The report detailed that Russian businessman Umar Kremlev spent hundreds of thousands of dollars to cover private island rentals and fireworks for the event. Kremlev serves as president of the International Boxing Association and maintains close ties to Russian President Vladimir Putin, having travelled to China with Putin shortly before the Bahamas gathering. Trump Jr. and his wife confirmed on Instagram that Kremlev hosted two nights of post-wedding celebrations, describing him as a personal friend. President Donald Trump, who did not attend the ceremony, stated on 18 September that his son had reimbursed the Russian businessman.
“A toaster is a wedding gift. A private-island party paid for by a Putin-connected oligarch is something else.”
Scrutiny of family business ventures
In addition to the wedding celebrations, Curtis urged the committee to investigate other commercial activities managed by Donald Trump Jr. during his father's presidency. The senator pointed to Trump Jr.'s promotion of family-backed cryptocurrency ventures, international real estate deals involving direct discussions with foreign heads of state, and investments in defense contracting. Curtis also identified financial and advisory roles tied to prediction market platforms subject to regulatory decisions by the Commodity Futures Trading Commission. Representative Robert Garcia, the ranking Democrat on the House Oversight Committee, confirmed that House Democrats launched a separate investigation into the wedding expenses last week.
“It's baffling that the son of a president would even think about allowing a Russian oligarch to bankroll his wedding.”
Party divisions and public polling
The push for hearings occurs six weeks prior to the 3 November 2026 midterm elections, in which the Republican Party is defending thin majorities in both chambers of Congress. Unlike Republican Senate candidates Ashley Hinson and Mike Rogers, who publicly urged an end to the war in Iran on 21 September, Curtis won election to the Senate in 2024 and does not face voters again until 2030. Public sentiment reflects widespread concern over official conduct, with a September 2026 Gallup survey recording that 89% of Americans view corruption as widespread within the federal government. Polling from Reuters and Ipsos conducted during the same week registered public approval for Donald Trump at its lowest level of his presidency.
