Tens of thousands of demonstrators took to the streets across Southern California on Saturday to voice their concerns over ongoing immigration raids and oppose the policies of President Trump, who they depicted as an aspiring monarch.

The organized opposition was timed for the day President Trump is hosting a rare U.S. military parade in Washington that's taking place on his 79th birthday.

More than 1,500 events were announced throughout the U.S. to send a loud message to President Donald Trump: “In America, we don’t do kings.”

Protesters began gathering early on the west steps of the state Capitol in Sacramento as a so-called “No Kings” protest against Trump administration policies, part of a nationwide day of demonstrations meant to coincide with a military parade marking the 250th anniversary of the U.

Millions marched in cities across the U.S. on Saturday as part of the nationwide "No Kings" demonstrations, according to event organizers

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

Thousands gathered in Daley Plaza and in suburban events in protests timed to coincide with a military parade in Washington celebrating the Army's 250th anniversary and President Donald Trump's 79th birthday.

Around 2,000 protests were planned on Saturday in opposition to President Donald Trump. Large crowds turned out in cities like Portland, Denver, Chicago, Houston and Los Angeles – and in smaller communities in traditionally conservative areas.
