The federal government may spend as much as $45 million on the event, which falls on Trump's birthday but officially honors the U.S. Army's 250th birthday

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. Yet it still reflects global traditions that serve a range of political and cultural purposes.

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.

Donald Trump's military parade in DC for his 79th birthday celebration currently has major hype across the United States.

President Donald Trump has already eroded many of the U.S.'s democratic safeguards and traditions in the initial months of his second term.

Many GOP officials appear to have no idea what to say about the president's military parade — and some don't want to attend the festivities, either.
