PHILADELPHIA (AP) — Cities large and small were preparing for major demonstrations Saturday across the U.S. against President Donald Trump, as officials urge calm, National Guard troops mobilize and Trump attends a military parade in Washington to mark the Army’s 250th anniversary.

Why are people protesting today and what is "No Kings"? Here's everything to know from locations to livestreams.

The largest is expected to take place in Portland, where at least five separate demonstrations are planned in and outside of downtown. Two downtown events will happen on Naito Parkway. One will gather at the Salmon Street Springs and another will form at the Battleship Oregon Memorial in Tom McCall Waterfront Park.
