New York Attorney General Letitia James has launched an inquiry into potential insider trading linked to former President Donald Trump's inner circle. The investigation focuses on allegations that Wall Street and U.S. politicians received advance information about changes in tariff policies before the wider market, enabling them to trade on non-public information. Reports indicate that updates on tariff deals were leaked to select financial actors, raising concerns about market fairness. This development follows confirmations from media outlets that certain market participants had early access to tariff news, prompting the New York AG to probe possible illegal trading activities connected to these leaks.
