Bo Hines, a former crypto adviser to US President Donald Trump who subsequently joined stablecoin issuer Tether, reportedly retained a one-third stake in the investment firm Nxum while advocating for the passage of the GENIUS Act. According to a Wall Street Journal report, Hines maintained contact with his business partners via Signal during his tenure at the White House, updating them on legislative progress. The report states that Nxum received $6.3 million from Tether as part of a deal, with the first payment processed while Hines was still serving in government.

The GENIUS Act, which passed Congress and was signed into law in July 2025, establishes regulatory frameworks for stablecoins. Hines attended the signing ceremony and was personally recognized by President Trump. Following his departure from the administration, Hines became a strategic adviser at Tether in August 2025 and assumed the role of CEO for its US arm the subsequent month. The legislation requires further rulemaking from agencies including the Office of the Comptroller of the Currency, Federal Deposit Insurance Corporation, Federal Reserve Board, and Treasury Department, with full implementation scheduled for January 2027.

Hines allegedly instructed an Nxum partner to characterize Republican lawmakers opposing the bill as “undermining the president” and influenced by entities such as Coinbase and a16z. This development intensifies scrutiny regarding potential conflicts of interest within the administration’s digital asset policy. President Trump previously disclosed earning $1.4 billion from investments tied to digital assets in 2025, including proceeds from World Liberty Financial, the family’s crypto company behind the USD1 stablecoin. Cointelegraph sought comment from Tether but did not receive an immediate response.
