Republican Senator John Curtis Calls for Probe into Trump and Biden Sons' Crypto Ties

Lawmaker Seeks Investigation into Presidential Family Business Interests

Republican Senator John Curtis of Utah has formally requested that the Senate Judiciary Committee investigate the crypto business activities and foreign dealings of Donald Trump Jr. and Hunter Biden.

In a letter sent Monday to committee Chair Chuck Grassley and Ranking Member Dick Durbin, Curtis called for an inquiry into how presidential family relationships might be used for private financial gain. He specifically asked for subpoenas to be issued for both men.

While many Democrats have previously pushed for probes into the Trump family’s cryptocurrency ventures, Curtis argues that the issue crosses party lines due to its potential impact on government ethics.

Key Points of the Request

• Curtis cites Donald Trump Jr.'s acceptance of gifts from Russian oligarch Umar Kremlev, which the Trump family has since repaid.
• The letter highlights Trump Jr.'s "active promotion of family-backed cryptocurrency ventures" and advisory roles with prediction market platforms.
• Curtis demands a similar investigation into Hunter Biden for substantial business with foreign entities and instances where his father’s presidency may have been used to provide value.
• The goal is to determine if existing ethics and anti-corruption laws were broken and to identify reforms to prevent the presidency from being used for private enrichment.

Regulatory Concerns and Context

The senator’s letter notes that certain companies Donald Trump Jr. is involved with fall under the regulatory jurisdiction of the Commodity Futures Trading Commission (CFTC), the US agency that regulates derivatives and prediction markets. The president recently stated that his son reimbursed Kremlev for what were described as "generous wedding gifts" from the Russian billionaire.

Regarding Hunter Biden, the letter references the pardon President Joe Biden granted his son in December 2024 for crimes committed or taken part in over the previous decade. Curtis noted that Hunter Biden has denied involving his father in his business dealings.

Political Backdrop and Crypto Legislation

This request comes shortly after Senate Republicans failed to pass the Digital Asset Market Clarity Act, a bill designed to establish market structure rules for the cryptocurrency industry. The legislation had stalled largely due to disagreements over ethics provisions. Some Democrats argued that the proposed measures were insufficient to prevent conflicts of interest, citing that President Trump disclosed earning $1.4 billion from digital asset-related ventures in 2025.

Lawmakers have frequently debated potential conflicts of interest surrounding Trump’s memecoin, his family’s World Liberty Financial business, and a $500 million deal tied to Abu Dhabi’s royal family.

What Happens Next

It is currently unclear if the Senate Judiciary Committee will move forward with the investigation. Curtis, who is serving his first term and is not up for reelection until 2030, has outlined a straightforward purpose for the inquiry: establish the facts and identify necessary legal reforms.
