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

Leading up to the military parade in Washington, D.C. Saturday, as many as 2,000 cities erupted in a coordinated, nationwide protest.

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

Thousands of people are gathering at sites across Pierce County on Saturday for No Kings events.

The parade is expected to include about 6,600 soldiers, 50 helicopters and 60-ton M1 Abrams battle tanks, as well as possibly 200,000 attendees and heightened security to match.

A flagship "No Kings" march and rally are planned in Philadelphia, but no events are scheduled to take place in Washington, D.C., where the military parade will take place on Trump's 79th birthday. Organizers of the protests say they want to take attention away from the parade.

"We built this country strictly on the no 'No Kings' rule."

New York City saw thousands attend demonstrations against the Trump administration Saturday, just hours before a military parade in Washington, D.C. MSNBC host Antonia Hylton is joined at the New York City “No Kings Day” protest by actor and activist Mark Ruffalo,
