SEC Enforcement Chief Resigns in Protest as Enforcement Policy Shift or Internal Rift Becomes Flashpoint

According to Reuters, Margaret Ryan, former head of enforcement at the U.S. Securities and Exchange Commission (SEC), abruptly resigned on March 16 after serving just six months in the position.

Sources familiar with the matter indicate that Ryan sought to bring fraud charges against individuals within Trump's circle, but faced resistance from SEC Chair Paul Atkins and other Republican-appointed officials, ultimately leading to her departure in protest.

Two cases in particular have escalated tensions between Ryan and SEC leadership, especially those involving cryptocurrency entrepreneur Justin Sun and Tesla CEO Elon Musk. Both maintain close ties to Trump, with Musk having previously served as a White House special advisor.

In the case against Justin Sun, the SEC initially filed suit in March 2023 against him and three companies under his control, alleging the sale of unregistered securities and participation in manipulative wash trading.

However, the case was settled early this month for a $10 million penalty. Under these circumstances, Justin Sun and his companies neither admitted nor denied the truthfulness of the SEC's allegations.

It is reported that Justin Sun became the largest investor in the Trump family's cryptocurrency project World Liberty Financial in November 2024, and increased his total holdings to $75 million in January 2025.

Notably, although enforcement officials indicated that Ryan supported this settlement proposal, her signature does not appear on the settlement court documents.

Another controversial case involves the SEC filing suit against Musk in January 2025, alleging he failed to disclose his beneficial ownership in the acquisition of Twitter (now X) in early 2022, thereby allowing him to increase his original stake at a low price and become a major shareholder of X.

Some lawyers have pointed out that although both cases have strong evidence and favorable likelihood of success, the SEC's ultimate handling of these cases has also become a focal point of the disagreement between Ryan and leadership.

In summary, Ryan's resignation reflects that under Trump administration leadership, the SEC's policy regarding crypto-related cases is undergoing transformation, and the agency faces complex internal contradictions and challenges in handling complicated cases with political associations.
