U.S. Senator Elizabeth Warren has urged the Securities and Exchange Commission (SEC) to investigate World Liberty Financial, a company linked to the Trump family, for potential securities law violations. In a letter to SEC Chair Paul Atkins, Warren expressed concerns over the company's use of its own token as collateral for a $75 million loan, despite prohibiting investors from selling the token. She questioned whether the token should be classified as a security and requested a response from the SEC by May 26.
