Members of the U.S. Senate Committee on Banking, Housing and Urban Affairs minority, led by Ranking Member Elizabeth Warren, sent a letter to Securities and Exchange Commission (SEC) Chair Paul Atkins urging the SEC to open an investigation into whether President Trump and associated insiders violated securities laws in connection with tariff announcements that triggered market volatility. The letter asks the SEC to examine whether President Trump, cabinet members, donors, other insiders and Administration officials engaged in insider trading, market manipulation, or other violations, including whether any insiders had advance knowledge of a tariff pause and traded ahead of the public announcement. The senators cite a Truth Social post at 9:37 am stating “THIS IS A GREAT TIME TO BUY!!! DJT” and note that the official announcement of a tariff pause followed about four hours later at 1:18 pm. The senators also request information on how Trump Administration cuts to the SEC could affect the agency’s capacity to respond to large-scale market events and pursue enforcement actions, and they ask for responses by April 25, 2025.
