As millions of Americans protested at “No Kings” rallies across the country, onlookers gathered in Washington on the president’s birthday for a muted celebration.

Flying home from his first visit to Paris as president, an awestruck Donald Trump told aides aboard Air Force One that the military parade he’d just witnessed was one of the most dazzling spectacles he’d ever seen.

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.
