PHILADELPHIA — 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.

Millions of people turned out for "No Kings" protests nationwide on Saturday that were largely peaceful though there were some arrests and police had to disperse unruly crowds, including in Georgia and Los Angeles.

Across the country, relatively few disruptions were reported during protests and marches where the mood ranged from joyful to defiant.
