News Portal, March 30 – U.S. Senator Richard Blumenthal sent a letter to SEC Chairman Paul Atkins questioning the short tenure of former enforcement chief Margaret Ryan and the reasons for her departure, expressing concern over the SEC dropping charges against Tron founder Justin Sun. Ryan took office in September 2025 and left in March 2026, serving only 6 months. In his letter, Blumenthal stated that her sudden departure raised many questions, especially amid reports that senior SEC officials had intervened in enforcement actions to limit the pursuit of cases involving certain cryptocurrency companies. Media reports indicate that Ryan had attempted to strengthen investigations into fraud-related cases, including those involving individuals connected to President Trump, but faced opposition from some Republican leaders on the committee. In the case of Justin Sun, disagreements became even more apparent. Previously, under the Biden administration, the SEC accused Justin Sun and related companies of issuing unregistered securities through TRX and BTT tokens, and of market manipulation via wash trading, as well as paying celebrities for promotion without disclosure. In the current administration, the SEC has dropped several enforcement actions against cryptocurrency companies, including a certain CEX, prompting market attention to shifts in regulatory direction.
