U.S. Senator Richard Blumenthal has put major crypto players on notice, sending compliance letters to Binance and Tether that demand records by January 4, 2027. The letters, dated November 5, 2026, are part of the Senate Permanent Subcommittee on Investigations’ widening probe into potential illicit cryptocurrency use, conflicts of interest, and crypto business ties to the Trump family.
Blumenthal warned that none of the four crypto firms—Binance, Tether, World Liberty Financial, and Fight Fight Fight LLC—had supplied documents over the previous 18 months. While the requests are voluntary for now, he said the subcommittee would have “no choice but to consider alternative measures to obtain compliance” if the January deadline passes. Because Democrats are set to take control of the Senate when the new Congress convenes on January 3, 2027, Blumenthal is poised to become the subcommittee’s chair one day before his deadline, giving him subpoena authority and a concrete enforcement timeline.
The Binance investigation is focused on the exchange’s alleged role in $1.7 billion of transfers to Iran. Tether, meanwhile, faces questions over its reported payment of roughly $6.3 million to Nxum, a consulting firm co-founded by Bo Hines, who was executive director of the President’s Council of Advisers on Digital Assets when the first payment arrived in May 2025. Hines, who kept a one-third stake in Nxum and later became head of Tether US, also lobbied to extend the GENIUS Act compliance window for stablecoin issuers from 18 months to 36 months, according to The Wall Street Journal. Nxum has denied that Hines was involved in its Tether work while in government.
World Liberty Financial and Fight Fight Fight LLC face a separate but related deadline of November 30, 2026 to begin producing documents. That Trump-linked crypto investigation has been open since May 2025 and includes scrutiny of foreign investors, possible ethics and legal violations, and the TRUMP coin. The broader letters also went to Homeland Security Secretary Markwayne Mullin, FCC Chair Brendan Carr, and donors to Trump’s White House ballroom project, including Amazon and Apple.
The outcome could shape future compliance and transparency expectations across the digital asset industry, especially for exchanges, stablecoin issuers, and politically connected crypto ventures.
