PANews reported on February 15 that Fox Business reporter Eleanor Terrett tweeted that Tether is working with U.S. lawmakers to influence how the U.S. regulates these fiat currencies. Tether, the issuer of the world's largest stablecoin USDT, has been controversial for its alleged lack of transparency. Critics say the company has never been fully audited, but instead chooses to have global accounting firm BDO provide quarterly financial book reviews.

As Congress works to enact legislation to establish a regulatory framework for stablecoins in the United States, Tether CEO Paolo Ardoino said the company is actively communicating with lawmakers to promote relevant bills and is committed to complying with the laws that are ultimately passed. The bill is expected to be signed into law by President Trump as early as April. If passed, Tether will be required to undergo monthly audits by U.S. accounting firms and maintain a one-to-one reserve with regulatory-approved assets.
