US Democratic Senator Richard Blumenthal is escalating a congressional investigation, again demanding documents from major crypto industry players and companies tied to President Donald Trump. Blumenthal sent letters to Binance, Tether, World Liberty Financial (WLFI), and Fight Fight Fight LLC — the issuer of Trump's meme coin — notifying them to produce outstanding materials by January 4, 2027.
The request is more than a routine written inquiry. Blumenthal warned that if the companies do not cooperate voluntarily by the deadline, the Senate Permanent Subcommittee on Investigations could consider compulsory measures, including subpoenas. He is expected to chair the subcommittee when the new Congress convenes in January, with Democrats securing a Senate majority, giving him even broader investigative powers.
The issues differ by target. For Binance, the focus is on allegations that it facilitated transactions with sanctioned entities linked to Iran and Russia, whether it has complied with a past settlement with US regulators, and the effectiveness of its anti-money laundering (AML) procedures. Blumenthal previously requested documents in February of this year related to $1.7 billion in transactions tied to sanctioned networks. Tether faces allegations that its USDT stablecoin was used within Iran's financial system. In a September report, Blumenthal argued that USDT played a role in Iran's shadow finance structures, and in October he opened a further inquiry into payments linked to a consulting firm connected to a former White House crypto adviser. The allegations have not been established as criminal violations, and the congressional review is ongoing.
The investigation into the two Trump-linked companies centers on ownership structure, foreign investment, and possible financial ties to the Trump family. Blumenthal began the probe in May 2025, raising questions about the relationship between World Liberty Financial and the TRUMP coin. Reports that $500 million in United Arab Emirates-linked funds were invested in World Liberty Financial have since heightened concerns about foreign influence on the US political and economic process, and other lawmakers have separately asked federal agencies to review national security risks. The companies' banking relationships have also drawn scrutiny over potential conflicts of interest and the need for tighter regulation.
Note: World Liberty Financial and Fight Fight Fight LLC were given an initial submission deadline of the 30th of last month, while the final deadline applying to all targeted companies is January 4, 2027.
No immediate sanctions or subpoenas have been issued so far. Congressional investigations typically begin by requesting voluntary cooperation and escalate pressure gradually if companies fail to comply. Whether the January 4 deadline leads to actual compulsory measures will therefore depend on how diligently the companies produce documents and how the investigation proceeds. Blumenthal's office views the request as a pivotal test of cooperation.
The matter arises at the intersection of congressional debate over crypto regulation legislation and the scope of the US Securities and Exchange Commission's enforcement authority, as well as the financial interests of crypto policy and Trump-family-linked businesses. With Democrats set to hold investigative power as the new Congress begins, regulatory uncertainty is expected to persist for crypto exchanges, stablecoin issuers, and politically connected digital asset ventures. Industry observers say sanctions and AML compliance records and foreign investment structures could directly affect business conditions in the US market going forward.
