Tether co-founder Phil Potter has made a $500,000 donation to the Commonwealth Unity Fund, a super-PAC supporting John E. Deaton, a lawyer who has been a vocal advocate for the cryptocurrency industry. Deaton is running for a seat in the Massachusetts State Senate as a pro-crypto candidate. He has represented Ripple Labs in its ongoing legal battle with the U.S. Securities and Exchange Commission (SEC). The SEC has accused Ripple of selling unregistered securities in the form of its XRP token. Deaton has argued that XRP is not a security and that the SEC's case is politically motivated. The donation from Potter is a significant sign of support for Deaton's candidacy and for the pro-crypto movement. It is the largest single donation that the Commonwealth Unity Fund has received to date. Potter is a co-founder of Tether, the company that issues the USDT stablecoin. Tether is the most widely used stablecoin in the cryptocurrency market. The donation from Potter has raised some eyebrows, as Tether has been the subject of controversy in the past. Some critics have alleged that Tether has not been fully transparent about its reserves. However, Potter has defended Tether's operations and said that the company is committed to transparency.
