The U.S. Senate Committee on Banking, Housing and Urban Affairs minority publicised a letter from Democratic Leader Chuck Schumer and Senators Ron Wyden, Elizabeth Warren and Adam Schiff asking the National Association of Attorneys General to investigate whether President Trump, his family, members of his administration or members of Congress violated state laws through insider trading or market manipulation linked to recent tariff policy changes. The request points to sharp market moves around the tariff announcements and subsequent partial pause, including the S&P 500 losing more than USD 5 trillion in market value within four days after the 2 April 2025 tariff announcement. The senators highlighted President Trump’s 9 April 2025 Truth Social posts, including “THIS IS A GREAT TIME TO BUY!!! DJT” shortly before he posted that he would pause some of the newly imposed tariffs, after which markets rose and the S&P recorded its biggest single-day jump in nearly 20 years. The letter argues state attorneys general are positioned to examine potential misconduct under state laws covering areas such as fraud, corruption, falsified records and consumer protection, and calls for any proven violations to be prosecuted and punished to the fullest extent permitted under state law.
