The military parade to mark the Army’s 250th anniversary and its convergence with President Donald Trump’s 79th birthday are combining to create a peacetime outlier in U.S. history.

President Trump is hosting a parade celebrating the 250th anniversary of the U.S. Army on Saturday, bringing tanks and soldiers to the streets of Washington, D.C., for the capital's first major military parade in more than three decades.

As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

Much of the central and eastern parts of the U.S. will experience rain showers and scattered thunderstorms, forecasters said.

U.S. Capitol Police arrested about 60 veterans Friday evening during a protest of the appearance of troops in an Saturday’s Army celebration in Washington and at immigration protests in Los Angeles.

President Trump's military parade for the Army's 250th anniversary faced criticism from "The View" co-host Sara Haines, who compared it to North Korean marches.

On Saturday, for the first time in more than 30 years, the U.S. military is holding a big parade. The event is intended to celebrate the 250th birthday of the Army and to remind Americans of their debt to men and women in uniform.

The Army plans an elaborate display of armor, artillery and aircraft for its 250th anniversary parade June 14.
