  • "The ads employed a series of divisive messages aimed at breaking through the clutter of campaign ads online, including promoting anti-Muslim messages."

Today at 12:15 p.m., Senate Intelligence Chairman Richard Burr (R-N.C.) and Vice Chairman Mark Warner (D-Va.) will hold a press conference "on the status of the Committee's inquiry into Russian interference in the 2016 U.S. elections."

  • The committee on Monday received a thumb drive of Russia-linked ads from Facebook, which today begins an advertising campaign promoting the company's nine-point plan to deter "election interference."

Don't be surprised if COVID metrics plunge over the next few days, only to spike next week.

Why it matters: The COVID Tracking Project warns of a "double-weekend pattern" on Thanksgiving — where the usual weekend backlog of data is tacked on to a holiday.
