Senator Blumenthal demands Cantor Fitzgerald records on Tether ties and Lutnick payments
Senator Richard Blumenthal asked Cantor Fitzgerald to hand over Tether partnership records by October 23, 2026, and to account for payments to Howard Lutnick's family.
Why it matters
A ranking Democrat on the investigations subcommittee now has oversight reach over a stablecoin issuer and its US reserve custodian, and the request for a disclosure deadline keeps the issue live into the November election. If the hearings or a Treasury or Justice Department inquiry follow, US federal agencies would be examining sanctions compliance around USDT, which is the settlement asset for much of the Iran-linked activity the subcommittee describes.

CoinDesk reported the letter was sent Thursday without a date, Crypto.News dates it to October 8, and Cointelegraph also gives Thursday, so the two explicit dates and the weekday point to the same delivery.

What happened
Senator Richard Blumenthal, the ranking Democrat on the Senate Permanent Subcommittee on Investigations, sent a letter on October 8 to Cantor Fitzgerald chairman Brandon Lutnick requesting records on the bank's partnership with Tether, its custody services and how it monitors the stablecoin issuer against banking and sanctions law. Cantor holds and manages Tether's US Treasury reserves and acquired rights to a 5% stake in Tether in 2024, and Cointelegraph reported the bank custodies tens of billions of those reserves. Blumenthal's letter, which set an October 23, 2026 deadline for response, followed a September report by Democratic subcommittee staff alleging USDT has become a key tool for Iran's shadow banking network, and he called on the Treasury and Justice Department to investigate possible sanction violations. Blumenthal alleges the value of Cantor's stake rose from about $600 million to $10 billion since Trump returned to office, and that Howard Lutnick, the Commerce Secretary who left Cantor to join the administration and handed the company to his son, received more than $250 million in that period including a $192 million distribution. Tether said it has worked with law enforcement for years and has frozen nearly $550 million in Iran-linked USDT in 2026, and Cointelegraph reported that neither Cantor nor Tether gave an immediate response to its request for comment. The letter does not establish that either company broke US law, and Crypto.News noted that independently of Blumenthal's estimate, Cantor holds five percent of Tether.
