According to TechFlow, Tether has published letters to the U.S. Senate, the Committee on Housing and Urban Affairs, and the U.S. House of Representatives Financial Services Committee, outlining its "commitment to security and a close working relationship with law enforcement."
In a recent letter, Tether CEO Paolo Ardoino highlighted Tether’s recent decision to ban USDT from being used in all wallets on the Office of Foreign Assets Control (OFAC) sanctions list.
Tether claims to have helped the U.S. Department of Justice, the U.S. Secret Service, and the Federal Bureau of Investigation (FBI) freeze 326 wallets controlling 435 million USDT so far, although the tokens in the latest frozen wallets appear to be far less than this number. Ardoino also announced that Tether "recently included the U.S. Secret Service on our platform and is doing the same for the FBI."
