2020 Democratic Presidential candidate Senator Elizabeth Warren speaks as she attends a rally at the Kings theatre on January 7, 2020 in New York.

Presidential contender Elizabeth Warren is demanding a federal investigation into whether President Donald Trump provided advance notice of the deadly strike on Iran's Gen. Qasem Soleimani to stock traders who may have profited illegally from the tip.

The Massachusetts Democratic senator made her demand in a letter dated Monday to the chairmen of the Securities and Exchange Commission and the Commodity Futures Trading Commission. It cited a Daily Beast report that Trump had told guests at his Mar-a-Lago resort days before the Jan. 3 strike to expect a "big" response to Iran "soon."

"If this report is true, it raises a number of troubling national security questions regarding President Trump's handling of classified and other sensitive national security information," Warren wrote in the letter, which was also signed by Sen. Chris Van Hollen, D-Md., the ranking member of the Senate subcommittee that oversees securities and investments.

The senators wrote that the president's Florida resort guests may have obtained "confidential market-moving information and had the opportunity to trade defense industry stocks or commodities or make other trades based on this information."
