On his 79th birthday, President Trump spent more than three hours on Saturday taking in the scene at a military parade commemorating the 250th anniversary of the U.S. Army.

Dissent against the parade is also coming partly from within one of Trump’s most reliable support bases: veterans. Although former U.S. military personnel have historically voted with wide margins in favor of Trump and the Republican Party, there is a growing discontent among some within the community.

Coinciding with Trump's 79th birthday, the parade will feature tanks, bands and thousands of troops in honor of the Army’s 250th anniversary celebration.
