Blumenthal Sets January Deadline for Binance, Tether and Trump Crypto Investigation

US Senator Richard Blumenthal has intensified congressional scrutiny of the cryptocurrency industry by demanding documents from Binance, Tether, and two crypto businesses linked to Donald Trump. The four companies have until January 4, 2027, to complete their voluntary submissions as the Senate investigates suspected illicit financial activity and potential conflicts of interest involving the Trump administration.

Blumenthal delivered the requests through letters dated November 5. He warned that companies failing to provide the requested records could prompt the Senate investigative panel to consider other ways of obtaining the information.

The inquiries cover separate concerns involving the companies. World Liberty Financial and Fight Fight Fight LLC, which is associated with the Official Trump memecoin, face questions about foreign investments and possible conflicts of interest. Binance and Tether are being investigated over alleged illicit cryptocurrency flows, including transactions reportedly connected to Iran.

Binance, Tether and Trump-Linked Companies Face January 4 Deadline

The latest letters extend a series of congressional efforts to obtain information from the four businesses following months of investigations and previous correspondence.

Blumenthal has established two deadlines for the document requests. Companies must begin producing the requested materials by November 30, while January 4, 2027, marks the final date for voluntary cooperation. He cautioned that failure to comply could lead the subcommittee to consider alternative enforcement options.

The latest correspondence does not announce formal subpoenas or immediate legal action. Instead, it gives the companies an opportunity to provide the requested information before lawmakers decide whether additional steps are necessary.

Blumenthal currently serves as the ranking member of the Senate Permanent Subcommittee on Investigations. He is expected to become its chairman after Democrats take control of the panel, potentially strengthening his ability to pursue further inquiries and compulsory document requests.

The investigation into Binance has been developing since February 2026, when Blumenthal first requested details about the exchange’s compliance systems and suspected Iran-related transactions.

In April, the senator renewed his demands and questioned whether Binance had accurately disclosed its efforts to identify and handle suspicious financial activity. Binance has rejected allegations concerning its compliance operations.

Tether Faces Questions Over USDT Transactions Linked to Iran

Tether’s involvement in the Senate investigation became more prominent after Democratic investigators published a report on September 28.

The report examined 846 cryptocurrency wallets that had been sanctioned or targeted for seizure because of their alleged connections to Iran and regional proxy organizations.

Investigators found that 84% of the identified wallets had used USDT exclusively or for nearly all their transactions. They argued that Tether’s stablecoin played a significant role in facilitating financial activity within Iran’s shadow banking network.

Tether has disputed those conclusions, maintaining that its compliance teams actively monitor suspicious transactions and freeze wallets connected to illicit activities.

CEO Paolo Ardoino also defended the company’s response, claiming that Tether froze addresses associated with Iran an average of four weeks before official sanctions designations were issued.

The latest document demands could give lawmakers a closer look at how Tether monitors transactions, identifies suspicious wallets, and responds to potential sanctions violations.

World Liberty Financial and TRUMP Memecoin Face Congressional Questions

Blumenthal’s separate investigation into Trump’s cryptocurrency interests centers on World Liberty Financial and Fight Fight Fight LLC.

The senator opened the inquiry in May 2025 after concerns emerged about possible conflicts between Trump’s financial interests and his responsibilities as president.

The investigation is examining foreign investments, overseas financial relationships, and potential violations of government ethics requirements.

Fight Fight Fight LLC is associated with the Official Trump memecoin, while World Liberty Financial is another cryptocurrency business connected to the Trump family.

The inquiry previously received public attention during a July 2026 forum organized by Blumenthal. The hearing examined the family’s cryptocurrency ventures and featured testimony from TRUMP token investors who said they had lost thousands of dollars.

The latest requests highlight two major areas of concern for congressional investigators. Binance and Tether are facing questions about potentially illicit cryptocurrency transactions and sanctions-related activity, while Trump’s crypto businesses are being examined over foreign financial connections and possible conflicts of interest.

The January 4, 2027, deadline represents an important milestone for all four companies. As Blumenthal prepares to take leadership of the investigative subcommittee, the pressure to disclose relevant records is increasing.

Whether the companies cooperate voluntarily or face stronger congressional measures could shape the next stage of the Senate’s investigations into some of the cryptocurrency industry’s most prominent businesses.
