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.

The largest "No Kings" protest on June 14 is expected to take place in Philadelphia as a nod to the country's history and to avoid accusations that protesters are opposing the Army parade in the nation's capital, organizers have said.
