Sens. Elizabeth Warren (D-Mass.) and Chris Van Hollen (D-Md.) sent a letter to federal regulatory agencies on Monday asking them to investigate whether there was insider trading stemming from President Trump telling guests at his Mar-a-Lago club to expect a “big” response to Iran’s killing of an American contractor in Iraq, as The Daily Beast first reported.

Why it matters: The letter, sent to the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC), says the report "raises a number of troubling national security questions regarding President Trump's handling of classified and other sensitive national security information."

  • Warren and Van Hollen suggest that the advanced knowledge Mar-a-Lago guests received may have resulted in "illegal trading in defense company stocks or commodities."
  • Northrop Grumman and Lockheed Martin's stock prices both increased after the killing of Iranian Gen. Qasem Soleimani.
  • “These private individuals ... would have had the opportunity to obtain significant profits simply by being guests or members at President Trump’s private resort,” Warren and Van Hollen write in the letter.

What's next: The senators asked the agencies for a briefing no later than Feb. 13.

Black Friday shopping up from 2020 but trails pre-pandemic levels

More shoppers flocked to stores on Black Friday this year compared to last, but online shopping was lower than expected, according to data from Friday.

Driving the news: Online shopping was on the lower end of what was expected, largely because people had been ringing up their shopping carts earlier in the year in an effort to skirt potential supply chain issues, according to the Adobe Digital Economy Index.

Trump can't quit mainstream media

Bob Woodward and Robert Costa issued a rebuttal on Friday to a statement by former President Donald Trump that misrepresented their reporting — and once again showed the 45th president's thin skin about mainstream media.

Driving the news: "Former President Trump said ... our book, 'Peril,' implied that he was planning to go to war with China," the statement begins. "[W]e report that Chairman of Joint Chiefs Mark Milley 'believed that Trump did not want a war' before or after the 2020 election."
