The parade, which falls on Trump’s 79th birthday, kicked off earlier than expected with thunderstorms forecast in the Washington area.

Opponents have criticized the parade as a show of authoritarian power and unnecessary expenditure, particularly as Trump champions cost-cutting measures in the federal government.

Nationwide ‘No Kings’ protests

Earlier, a significant number of individuals rallied in Washington and other cities to oppose Trump’s policies. The protests were predominantly peaceful and represented the largest expression of opposition to Trump’s administration since his January return.

In Los Angeles, however, police, some on horseback, used flash-bang grenades and tear gas to push back a crowd of protesters around the federal building that has been a focus of much of the demonstrations.

Anti-Trump groups planned nearly 2,000 demonstrations across the country to coincide with the parade. Many took place under the theme “No Kings,” asserting that no individual is above the law.
