Senator John Curtis wants answers. He sent a letter Monday to Senate Judiciary Committee leaders Chuck Grassley and Dick Durbin, asking them to open a formal inquiry into the crypto dealings of Donald Trump Jr. and Hunter Biden — and he’s pushing for subpoenas against both men.
It’s a pretty striking move. Curtis, a Republican in his first Senate term, is essentially saying neither party’s presidential family gets a pass. He accused Trump Jr. of accepting gifts from Russian oligarch Umar Kremlev and of promoting cryptocurrency ventures tied to the Trump family name — activities that fall under the Commodity Futures Trading Commission’s oversight. Trump Jr. and his wife said they repaid Kremlev for what they called a “generous wedding gift.” No further details on that repayment were given in Curtis’ letter.
Hunter Biden’s Foreign Deals Under the Microscope
Curtis also wants a hard look at Hunter Biden’s foreign business dealings. Specifically, he’s asking whether Hunter used his relationship with President Biden to generate personal value. President Biden pardoned Hunter in December 2024, covering potential crimes over the prior decade. Hunter has long maintained his father played no role in his business arrangements.
Curtis isn’t framing the inquiry as a prosecution. He said the goal is to establish facts and figure out whether existing ethics or anti-corruption laws actually apply to these situations. He also wants to identify reforms — ways to close whatever gaps let presidential family connections become tools for private profit.
That’s the cleaner, more defensible framing politically. But the request still carries real weight. Subpoenas, if granted, would force document production and potentially testimony from both men.
The $1.4 Billion Number That Broke the Crypto Bill
Curtis’ move comes right after a notable legislative collapse. Republicans tried to push through the Digital Asset Market Clarity Act, a bill meant to lay out clear market rules for crypto. It didn’t make it. Democrats blocked it, and the reason they gave was Trump’s crypto-based profits — which reportedly hit $1.4 billion in 2025. That number was basically impossible for Democrats to ignore when voting on a bill the Trump administration wanted passed.
Republicans pushed back. They argued the bill actually contained stronger ethics provisions than Democrats were giving it credit for. Democrats didn’t buy it, said the provisions were insufficient, and the bill died. So now the broader crypto regulatory framework stays murky, and the political fight over who profits from digital assets keeps bleeding into the legislative process.
It’s a mess. And it’s not getting cleaner anytime soon.
Congress has seen calls before to probe the Trump family’s crypto connections, mostly from Democrats. Trump’s memecoin drew scrutiny. So did a large deal tied to Abu Dhabi’s royal family. But those efforts stayed pretty partisan. Curtis is trying something different — pulling Hunter Biden into the same frame and pitching the whole thing as a bipartisan accountability exercise.
Whether Grassley and Durbin actually move forward with the inquiry is unclear. No response from either senator’s office was included in the source material. And even if the committee agrees to act, the path from a letter to actual subpoenas to real testimony is long and uncertain.
What Curtis Is Really After
Curtis won’t face reelection until 2030, which gives him some room to take positions that might annoy parts of his own party. Going after Trump Jr. while also going after Hunter Biden probably plays better in a general-election framing than a pure partisan attack would. It’s probably also a genuine attempt to push the conversation about crypto ethics into territory that isn’t just Democrat-versus-Republican.
The crypto industry itself is watching all of this carefully. When $1.4 billion in presidential family profits becomes a reason to kill a market clarity bill, that’s bad for everyone trying to build legitimate businesses in the space. Regulatory uncertainty is already a persistent problem. Adding a layer of political scandal on top makes it harder for any serious legislation to move.
Curtis wants reforms. He wants to know if existing laws cover what Trump Jr. and Hunter Biden allegedly did, and if not, he wants new ones. Specific reform proposals weren’t detailed in the letter, but the direction is clear: tighten the rules around presidential family members using their connections to profit from financial markets, including crypto.
The Senate Judiciary Committee now has the letter. What it does with it — that’s the open question.

Why It Matters
This inquiry into the crypto dealings of high-profile political figures underscores the increasing scrutiny of cryptocurrency transactions and the potential risks associated with conflicts of interest in the political arena. As regulatory frameworks around digital assets continue to evolve, transparency in these dealings is crucial for maintaining public trust and ensuring accountability, particularly in a sector often criticized for its lack of oversight. Such actions may also influence market sentiment and regulatory approaches, as stakeholders assess the implications of political affiliations and financial conduct on the broader crypto landscape.
