Elon Musk posted a cryptic message about the "No Kings" protests after activists took to the streets across the U.S. over the weekend.

The event was one of more than 2,000 “No Kings” rallies held across the country on Saturday, protesting what organizers call “authoritarianism, billionaire-first politics, and the militarization of our democracy.

The "No Kings Nationwide Day of Defiance" is planned to "reject corrupt, authoritarian politics in the United States," organizers say.

Between activism, election results and protest turnout, the prevailing political winds suggest the backlash to the president is real.

In a city known as the cradle of American democracy, an impassioned, hourslong protest filled the streets for a 'No Kings Nationwide Day of Defiance.'

Additional celebrities including Anna Kendrick, Gina Rodriguez-LoCicero and Tessa Thompson were out on Saturday to protest against the Trump administration.

The “day of defiance” protests began as early as 10 a.m. in North Texas, while the Washington, D.C., military parade for the Army’s 250th birthday starts at 5:30 p.m. Central.
