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.

Crowds of protesters gathered nationwide Saturday for ‘No Kings’ protests, opposing President Donald Trump and his administration’s policies. The demonstrations coincided with the Army’s 250th anniversary parade,

From Silver Spring and Bethesda and Gaithersburg in Maryland, to Fairfax and Falls Church and Arlington in Virginia, people throughout the region came out for “ No Kings Day of Defiiance ” protests. (There was not a “No Kings” protest in DC itself, but there was a march from Logan Circle to the White House organized by Refuse Fascism .)

Around 1,800 protests are set to coincide with President Trump's military parade in Washington, D.C. yet none planned in the U.S. capital. Here's why.

Tight security ensured a family-oriented atmosphere at the U.S. Army's 250th anniversary parade despite liberal opposition and protests nearby.

On Saturday, a military parade will end with fireworks to mark the Army's 250th anniversary, which also happens to coincide with President Donald Trump's birthday and Flag Day. The 'No Kings' protest are set to counter what organizers say are Trump's plans to feed his ego on his 79th birthday.

“The most threatening sound to an oligarch is laughter.”
