The Washington Post editorial board in a new column says the 'No Kings' protests, like the tea party of 2009, are a warning to the president.

The DC protest was the largest in the Washington area, but there also gatherings throughout the DMV, including Arlington, Falls Church, McLean, Bethesda, Chevy Chase, and Silver Spring. According to organizers, more than 7 million people participated in more than 2,700 events in all 50 states.
