Senator John Curtis, a Republican from Utah, wrote the Senate Judiciary Committee September 21 asking it to investigate whether Donald Trump Jr., eldest child of President Donald Trump, has used his relationship with his father “for private financial benefit.”

In the letter (here), he writes that

For years, serious questions have been raised about members of presidential families using their names and proximity to the President to advance private business interests.

In a nod to fairness and bipartisanship, he asks the Committee to investigate Hunter Biden as well, but the bulk of his letter recounts the ways Don Jr. has used the family name to enrich himself. From the payment of a lavish wedding afterparty by a Russian oligarch, to his promotion of family-backed cryptocurrency ventures, the pursuit of international real estate deals, several reported investments in defense contracting.

“These reports raise legitimate questions about foreign access to members of a sitting president’s family and whether such relationships can create actual or perceived expectations of favorable treatment,” he writes. He then asks the Committee to “establish the facts, determine whether existing ethics, disclosure, or anti-corruption laws apply, and identify reforms necessary to prevent the presidency from becoming a vehicle for private enrichment by those closest to it.”

The letter is remarkable for two reasons. It puts the question of Presidential relatives trading on their link to the single most powerful individual in the modern world on the agenda at a time when it is likely to engage the public (and hence lawmakers), and it was written by a Republican. It’s unlikely the Committee will act before November, but, particularly if the Republicans suffer a major defeat in November, an investigation will surely be at the top of agenda in 2027.
