[U.S. Lawmakers Question TRON IPO, Urge SEC to Investigate Justin Sun] According to Cointelegraph, two U.S. Congress members have sent a letter to the Securities and Exchange Commission (SEC), requesting a response regarding issues that affect how crypto companies list on U.S. exchanges. Senator Jeff Merkley and Representative Sean Casten questioned the timing of the SEC's decision to drop its enforcement case against TRON founder Justin Sun in the letter. Justin Sun was sued in 2023 for allegedly issuing unregistered securities, but the SEC applied to suspend the case a month after former Chair Gary Gensler stepped down. The lawmakers believe that Sun's "large investments" in cryptocurrency projects controlled by the Trump family—such as World Liberty Financial and the meme token TRUMP—may have influenced the case's trajectory. Additionally, they raised concerns about TRON's July listing on Nasdaq through a reverse merger, citing financial and national security risks. They urged the SEC to ensure TRON meets the strict standards for listing on U.S. exchanges and questioned whether the SEC can "protect the American public" through settlement agreements. This letter may trigger broader scrutiny of similar listing practices by other foreign crypto companies.
