Senator Seeks Probe of US Presidents Sons Over Crypto Ventures

Senator John Curtis, a Republican from Utah, has requested an investigation into the financial activities of the US presidents’ sons, specifically targeting Donald Trump Jr. and Hunter Biden.

Curtis sent a letter to the leaders of the Senate Judiciary Committee, Chuck Grassley and Dick Durbin, advocating for a probe into the use of presidential family relationships for private financial gain, preferential treatment, or access by domestic and foreign interests. He also requested subpoenas for both individuals.

Curtis highlighted Donald Trump Jr.'s acceptance of gifts from Russian oligarch Umar Kremlev, his active promotion of family-backed cryptocurrency ventures, and his advisory roles with prediction market platforms. The senator noted that Donald Trump Jr. had reportedly repaid Kremlev for what was described as a wedding gift.

For Hunter Biden, Curtis cited substantial business dealings with foreign entities and instances where his connection to the presidency was invoked to provide value. Curtis also mentioned President Biden's pardon of his son in December 2024 for past alleged crimes, and Hunter Biden's denials of involving his father in his business dealings.

Curtis stated that the inquiry's purpose should be to establish facts, determine the applicability of existing ethics, disclosure, or anti-corruption laws, and identify necessary reforms. Calls for investigations into the Trump family’s crypto industry ties have previously come from House and Senate Democrats, who have sought probes into potential conflicts of interest.

This call for an investigation follows the Senate Republicans' failure to pass the Digital Asset Market Clarity Act, a bill intended to establish market structure rules for the crypto industry. Some Democrats cited concerns about President Trump using crypto to generate profit from the presidency as a reason for not supporting the bill.

President Trump had disclosed earnings of $1.4 billion from digital asset-related ventures in 2025. Republicans indicated that the president had agreed to stronger ethics provisions in the bill concerning his crypto investments, but many Democrats argued these measures were insufficient to prevent corruption.
