Millions are expected to gather in "No Kings" demonstrations in over 1,500 cities on Saturday, the same day the Army will celebrate its 250th anniversary on Trump's birthday.

Opponents of President Donald Trump's administration on Saturday rallied in nearly 2,000 locations across the country, with thousands demonstrating in Northern California.

The parade, honoring the Army’s long-planned 250th anniversary celebration and coinciding with Trump’s 79th birthday, is set to step off from the Lincoln Memorial under the threat of stormy weather in Washington and protests around the country tied to a turbulent week of immigration enforcement that has involved military deployment in Los Angeles.

Protests across U.S. held on the same day as the Army 250th anniversary parade, and Trump's birthday, in Washington, D.C.

The rally at Daley Plaza started at noon with a moment of silence for the shootings in Minnesota before moving into the streets of downtown Chicago.

Trump protests in Harrisburg, Lancaster, and thousands of other places throughout central Pennsylvania and the nation.

Protesters across Southern California and the country took to the streets for ‘No Kings’ demonstrations against President Trump and the $45-million celebration of the U.S. Army’s 250th birthday, which coincides with Trump’s 79th.

Protests are underway in Jacksonville and across the United States as part of the "No Kings" nationwide day of defiance. Watch live coverage here.

Protesters held signs that read, “No kings since 1776,” “Bad Things Happen When Good People Do Nothing,” “Stop the Parade Fund Medicaid,” “When cruelty becomes normal compassion looks radical” and “Make Orwell Fiction Again.”
