The Army expects as many as 200,000 people to attend the parade that honors the U.S. Army’s formation and coincides with Donald Trump’s birthday.

MSNBC host Chris Hayes couldn’t contain his laughter on air Friday while reading a fundraising email from President Donald Trump. The email asked for donations for his Saturday military parade, which, as it turns out, most Americans aren’t that eager to fund.

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.
