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

Thousands are gathering across the Bay Area on Saturday to protest against President Donald Trump---on his birthday. The day of protests coincides wit

The rallies were among hundreds of "No Kings" protests held throughout the United States, timed to coincide with a military parade celebrating the 250th birthday of the U.S. Army in Washington, D.C. Saturday was also Trump's 79th birthday.

The parade was the spectacle event Trump had long wanted. It also helped sparked the largest mass opposition to him since his inauguration 145 days earlier.

We implore everyone not to play into Trump’s hands and fall for his schemes,” the chair of the Washington State Democratic Party said in a statement.

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

While President Donald Trump attended a military parade he ordered on his birthday to recognize the 250th anniversary of the U.S. Army in Washington, D.C., thousands of people in the Kansas City metro area flexed their First Amendment right Saturday to voice their opposition to polices of the Trump administration during the “No Kings” national day of defiance.

Coordinated "No Kings" protests are underway from coast-to-coast, part of a "national day of peaceful protest" against the Trump administration that is expected to draw millions. Protesters in some areas braved wet weather to raise signs and chant slogans supporting the rights of immigrants and criticizing what they see as Trump's power grab.
