Lawmaker Requests Tether Documents on Nxum Transaction
Sen. Richard Blumenthal has asked Tether's chief executive for documents concerning a reported $6.3 million arrangement with Nxum, a marketing firm co-founded by former White House crypto adviser Bo Hines. The Senate Permanent Subcommittee on Investigations is reviewing the relationship and Hines's lobbying activity around stablecoin legislation. Blumenthal alleges Hines retained an ownership stake while serving in government and that Tether coordinated with Nxum on advocacy tied to the GENIUS Act.
The letter seeks agreements, payment records, correspondence and lobbying materials involving Tether and Nxum. Blumenthal, the subcommittee’s ranking Democrat, says the panel is reviewing the reported arrangement and Hines’s work on stablecoin legislation. He alleges Hines retained a one-third Nxum ownership share while leading the President’s Council of Advisers on Digital Assets and used encrypted messaging to coordinate advocacy.
The GENIUS Act creates stablecoin issuer and reserve requirements. Blumenthal says subcommittee-reviewed messages indicate Tether coordinated with Nxum on lobbying and that Ardoino told Nxum to “obliterate” opponents. Hines left government in August 2025 and later became Tether US CEO; Harry Jung moved from government to Nxum in 2026.
The inquiry could affect how stablecoin rules and crypto lobbying are perceived by users, investors and firms subject to the GENIUS Act. If the allegations prompt tighter disclosure or ethics scrutiny, companies may face higher compliance and reputational costs, while consumers could gain clearer information about who shapes digital-asset policy. The outcome may also influence public confidence in government-crypto relationships, though any effects depend on the investigation’s findings and election results.
