Blumenthal Asks Tether to Detail Every Payment to Nxum, Bo Hines’ Consulting Firm

Senate Subcommittee Demands Full Disclosure from Tether and Nxum

Senator Richard Blumentham, the ranking member of the Senate Permanent Subcommittee on Investigations, has issued letters to Tether and Nxum Group requesting a comprehensive set of documents. The request, dated Oct. 22, 2026, gives both firms until early November to provide contracts, payment details, and internal communications that link the stablecoin issuer to the consulting firm co‑founded by former White House crypto council director Bo Hines.

Why the Inquiry Matters

The letters build on a Wall Street Journal report that Tether paid Nxum more than $6 million after agreeing in May 2025 to a $415,000‑per‑month retainer. At the time, Hines was still serving in the White House, overseeing stablecoin policy. The Senate’s request focuses on three key concerns:

1. Potential conflicts of interest – Hines retained a one‑third ownership stake in Nxum while shaping federal crypto policy.
2. Lobbying transparency – The WSJ alleged that Tether directed Nxum to lobby on the GENIUS Act, seeking provisions that would extend Tether’s compliance timeline, a move the senator describes as the “Tether loophole.”
3. Financial flow tracing – Blumenthal asks Tether to break down every payment, including wallet addresses, to determine whether any funds were routed through third‑party firms such as the marketing agency Notorious before reaching Nxum.

What the Senate Is Asking For

Both letters set a Nov. 3, 2026 deadline and request the following from each entity:

• All contracts between Tether and Nxum covering the period Jan. 20 2025 – Aug. 9 2025.
• Itemized payment records, including dates, amounts, and cryptocurrency wallet addresses used for each transfer.
• Correspondence (emails, Slack messages, meeting notes) that mention Bo Hines, Nxum, or any Tether‑related lobbying activity.
• Details on any contemplated equity stake by Tether in Nxum, including the reported $56 million, 25 % purchase proposal.
• Evidence of lobbying registration – The letters note that Nxum never filed a formal lobbying report with the House or Senate, a potential violation of the Lobbying Disclosure Act.

Context and Next Steps

The inquiry arrives amid broader scrutiny of Tether’s operations. Earlier this year, Blumenthal urged the Treasury and the Justice Department to examine Tether’s alleged facilitation of Iranian transactions using USDT. The current request adds a layer of ethical and legal analysis, probing whether a stablecoin issuer leveraged a former regulator’s private firm to influence policy.

If Tether and Nxum comply fully, the Senate may use the material to assess whether existing ethics rules were breached and whether additional enforcement action is warranted. Non‑compliance or incomplete disclosures could trigger a formal subpoena or lead to a referral to the Department of Justice for further investigation.

Practical Takeaway

For market participants, the unfolding investigation underscores the importance of clear separation between public service and private consulting arrangements, especially in the fast‑moving crypto sector. Companies should audit their lobbying disclosures, ensure transparent payment trails, and be prepared to produce detailed records should regulators request them. As the deadline approaches, stakeholders will be watching closely for any revelations that could reshape the regulatory landscape for stablecoins and related advisory services.
