Senator Blumenthal Investigates Tether Payments to Firm Co-Owned by Former White House Crypto Adviser Bo Hines

Why it matters
The probe examines whether a stablecoin issuer made millions in payments to a firm part-owned by the official shaping the legislation that would regulate it, raising questions about conflicts of interest, ethics rules, and lobbying disclosure in crypto policy.

What happened
Senator Richard Blumenthal, the ranking Democrat on the Senate Permanent Subcommittee on Investigations, sent letters to Tether CEO Paolo Ardoino and Nxum Group CEO Todd Hines on October 22, 2026, demanding contracts, payment details, and communications by early November. The inquiry follows an October 14 Wall Street Journal report alleging Tether agreed in May 2025 to pay Nxum $415,000 monthly for strategic communications and lobbying, with more than $6 million moving overall. Bo Hines, then executive director of the White House Council of Advisers for Digital Assets and a key architect of the GENIUS Act, retained a one-third ownership stake in Nxum during his government service. Hines left the White House on August 9, 2025, and became CEO of Tether's new U.S. division the following month. Blumenthal's letters cite messages reviewed by the Journal showing Tether coordinating Nxum's lobbying on the GENIUS Act, with Ardoino allegedly demanding Nxum 'obliterate' the legislation's opponents. A Nxum representative stated Hines was not involved in the deal and received no Tether-derived funds while in government. The letters set a November 3 deadline according to Unchained, while Bitcoin.com reports November 6.
