White House crypto adviser Patrick Witt says he is 'optimistic and bullish' on Clarity Act as stablecoin fight resurfaces

Senator Richard Blumenthal, the ranking Democrat on the Senate Permanent Subcommittee on Investigations, has demanded that Tether CEO Paolo Ardoino hand over records on the stablecoin issuer's dealings with Bo Hines, the former White House digital assets adviser, and Nxum, the consulting firm Hines co-founded. The letter follows an October 14 Wall Street Journal investigation reporting that Nxum earned $6.3 million from a Tether deal struck in May 2025, when Tether agreed to pay a marketing firm, Notorious, $415,000 a month. Hines kept a one-third stake in Nxum while serving in the White House and helped craft the GENIUS Act, signed in July 2025. Blumenthal's inquiry has not established that Tether or Hines violated federal law.

Background

The dispute centers on the GENIUS Act, which President Donald Trump signed into law in July 2025 to establish a federal regulatory framework for dollar-backed stablecoins, according to cryptoslate.com. Hines was executive director of the White House's digital asset advisory council and a key architect of the legislation, decrypt.co reports; he left the White House on August 9, 2025, and Tether named him CEO of its new U.S. division the following month. According to Blumenthal's letter, which cited The Wall Street Journal, Tether agreed in May 2025 to pay Nxum $415,000 per month for strategic lobbying, public relations and other advisory services, at a time when Hines retained a one-third ownership interest in Nxum. The Journal reported that Tether initially routed payments through Notorious, a marketing company headed by Peter Vincer, and that most of the first payment went to a wallet used by Nxum, where it was split three ways; later payments went directly to Nxum after Hines left government. The Journal also reported that Hines urged lawmakers to double the law's compliance window from 18 to 36 months, a change that chiefly benefited Tether, and that messages it reviewed showed Hines sharing talking points about Republican holdouts with his Nxum partners. A Nxum representative told the Journal that Hines wasn't involved in the Tether deal while in government and did not receive any Tether-derived funds during that period. Tether said external counsel previously conducted an in-depth internal investigation that found no evidence of wrongdoing.

What happened

Cryptoslate.com reports that on October 22, Blumenthal, the ranking Democrat on the Senate Permanent Subcommittee on Investigations, demanded records on Tether's reported payments to Nxum, the consulting firm co-founded by Hines. Decrypt.co reports the letter was sent Thursday and gave Tether until November 3 to respond; cryptoslate.com says Blumenthal wants payment records and communications by November 6. In his letter to Ardoino, Blumenthal wrote that Tether's alleged multimillion-dollar payment to a firm controlled by the White House official primarily responsible for cryptocurrency policy implicates federal ethics, anticorruption and lobbying laws, according to cryptoslate.com. Decrypt.co reports Blumenthal wrote that the payment structure suggests Tether was likely well aware of the illegality and impropriety of paying a sitting official. According to cryptoslate.com, the senator alleged Hines joined discussions about the legislation while his business partners coordinated lobbying with Tether executives, and accused Hines of advocating changes to the GENIUS Act that would particularly benefit Tether, including provisions allowing foreign stablecoin issuers additional time to meet US regulatory requirements. Cryptoslate.com reports Blumenthal cited allegations that Nxum later offered Vincer more than $300,000 and a share of future payments in exchange for signing a nondisclosure agreement, and referenced claims that Tether considered buying a 25% ownership stake in Nxum for $56 million. Decrypt.co reports this is Blumenthal's second Tether-linked letter this month: on October 8 he asked Cantor Fitzgerald, Tether's reserve custodian and a 5% shareholder chaired by Commerce Secretary Howard Lutnick's son, for records on that relationship, following a report from his staff finding that most Iran-linked wallets used USDT. Tether responded by citing about $550 million in Iran-linked freezes, including $344 million in April, decrypt.co reports. Both outlets note the inquiry has not established that Tether or Hines violated federal law, and that the requests came from the subcommittee's Democratic minority.

Market impact

The sources provide no price, trading-volume or stablecoin-flow data tied to the inquiry, so no market reaction can be measured from them. The only figures present are the payments and proposals under scrutiny. Decrypt.co reports that Nxum has earned $6.3 million from the deal Tether struck in May 2025, and that Tether agreed to pay Notorious $415,000 a month. Cryptoslate.com, citing Blumenthal's letter and The Wall Street Journal, reports the same $415,000 monthly figure for strategic lobbying, public relations and other advisory services, and says the senator referenced claims that Tether considered buying a 25% ownership stake in Nxum for $56 million. Cryptoslate.com also reports allegations that Nxum offered Vincer more than $300,000 and a share of future payments in exchange for signing a nondisclosure agreement. On the enforcement side, decrypt.co reports Tether cited about $550 million in Iran-linked freezes, including $344 million in April, in response to Blumenthal's earlier letter to Cantor Fitzgerald, described as Tether's reserve custodian and a 5% shareholder chaired by Commerce Secretary Howard Lutnick's son. The commercial stakes described are structural rather than priced: cryptoslate.com notes that accommodations for foreign issuers carried considerable commercial significance for Tether because its flagship USDT stablecoin operates through an offshore issuance structure, and that the legislation created pathways for qualifying foreign issuers to serve US customers under specified regulatory conditions, plus a transition period before stricter restrictions on distributing foreign-issued stablecoins would apply. Neither source reports USDT redemptions, market share shifts or price moves following the letter.

Why it matters

The sources frame the inquiry as a test of how stablecoin policy was written rather than a finding of misconduct. Cryptoslate.com reports the controversy centers on the GENIUS Act and whether Tether's financial ties improperly influenced crypto policy, with Blumenthal seeking transaction records, associated cryptocurrency wallet addresses and communications to establish the purpose of the intermediary arrangement and identify the parties that ultimately received the funds. Decrypt.co reports the letter builds on the October 14 Wall Street Journal investigation and that Blumenthal also asked about a Nxum pitch deck saying Tether would buy a 25% stake in the firm for $56 million. The sources also describe a widening scrutiny pattern: decrypt.co reports a second Tether-linked letter this month, to reserve custodian Cantor Fitzgerald, following a staff report finding that most Iran-linked wallets used USDT, and notes Lutnick defended Tether at his confirmation hearing last year while Sens. Elizabeth Warren and Ron Wyden pressed him in April over a reported Tether loan to a trust for his children. Both sources caution that the inquiry has not established that Tether or Hines violated federal law and that the requests came from the subcommittee's Democratic minority, meaning the documents may or may not be produced. Tether's position, per decrypt.co, is that external counsel previously conducted an in-depth internal investigation that found no evidence of wrongdoing.
