Senators Warren, Wyden, and Colleagues Target Trump’s Steel Tariff Announcements and Stock Market Activity
WASHINGTON, D.C. — A group of Democratic senators, led by Elizabeth Warren (D-Mass.) and Ron Wyden (D-Ore.), has demanded a federal investigation into whether former President Donald Trump and his associates engaged in insider trading by leveraging non-public information about steel tariffs to profit from stock trades. In a letter addressed to the Securities and Exchange Commission (SEC) and the Department of Justice (DOJ), the lawmakers highlighted suspicious stock activity tied to companies like Nucor and U.S. Steel following Trump’s social media posts about tariff decisions.
The senators cited instances where Trump publicly teased tariff announcements on platforms like Truth Social, only to see shares of steel manufacturers surge shortly after. For example, a May 2024 post hinting at new tariffs coincided with a 12% jump in Nucor’s stock price within 48 hours. The letter questions whether Trump or his team possessed advance knowledge of policy moves, enabling them to execute timely trades.
“Using non-public government information for personal financial gain is illegal and erodes public trust,” the senators wrote, noting that Trump’s financial disclosures reveal millions in assets tied to steel-related investments. They emphasized the “urgent need” for the SEC and DOJ to scrutinize trading patterns, communications, and potential conflicts of interest.
While the SEC declined to comment on the request, a DOJ spokesperson confirmed receipt of the letter. Trump’s spokesperson dismissed the inquiry as “politically motivated,” accusing Democrats of “relentless harassment.”
The probe request aligns with broader scrutiny of Trump’s financial dealings, including ongoing investigations in New York and Georgia. Legal experts suggest that proving insider trading would require demonstrating a direct link between policy decisions and trades—a high bar, but one the senators argue is worth pursuing given the “unprecedented pattern” of market activity.
As the 2024 election looms, the call for transparency underscores growing tensions over accountability for presidential actions. The outcome of this investigation could set a precedent for how future administrations balance policy-making with ethical financial practices.
