Republican Senator Calls for Senate Probe into Sons of Trump and Biden Over Crypto Activities

Senator John Curtis, a Republican from Utah, sent a letter to Senate Judiciary Committee Chair Chuck Grassley and ranking member Dick Durbin asking the committee to investigate whether the sons of President Donald Trump and former President Joe Biden have leveraged their family connections for private gain in the cryptocurrency sector.

Specific allegations

Curtis cited several points in his request:

• Donald Trump Jr. allegedly accepted a wedding gift from Russian oligarch Umar Kremlev and promoted family‑backed cryptocurrency projects while serving in advisory roles for prediction‑market platforms regulated by the CFTC.
• Hunter Biden is accused of conducting “substantial business with foreign entities” and of potentially using his father’s office to add value to his ventures.

Requested actions

The senator asked the Judiciary Committee to issue subpoenas to both Donald Trump Jr. and Hunter Biden and to examine whether existing ethics, disclosure, or anti‑corruption statutes apply. He also called for recommendations on reforms to prevent the presidency from being used for private enrichment.

Political context

Calls for scrutiny of the Trump family’s crypto dealings have primarily come from Democrats, focusing on a family‑issued memecoin, the World Liberty Financial business, and a large deal linked to Abu Dhabi’s royal family. Curtis’s request marks a bipartisan push for oversight as the Senate debated the Digital Asset Market Clarity Act, a bill intended to set market‑structure rules for digital assets.

Recent developments

The request follows a recent failure of Senate Republicans to secure enough Democratic votes for the Clarity Act. Democrats expressed concerns that President Biden’s own crypto earnings—reported at $1.4 billion in 2025—highlighted the need for stronger ethics provisions.
