Demonstrators are gathering in cities across the U.S. against President Donald Trump. That’s happening Saturday as officials urge calm, National Guard troops mobilize and Trump attends a military parade in Washington to mark the Army’s 250th anniversary.

A flagship "No Kings" march and rally are planned in Philadelphia, but no events are scheduled to take place in Washington, D.C., where the military parade will take place on Trump's 79th birthday. Organizers of the protests say they want to take attention away from the parade.

In the Greater Boston area, thousands of “No Kings” marches and rallies are taking place, part of major demonstrations planned across the country.
