Americans are demonstrating against President Donald Trump across the U.S. as counterpoint to the 200,000 people expected to attend the military parade in Washington.

Protesters clash with supporters of Trump's military parade in Washington, D.C., as they disagree over the president's authoritarian intentions.

The power of the US military will be sharply on display this weekend – on two different coasts and in two very different ways.

While many demonstrations against the Immigration and Customs Enforcement agency have been peaceful, with marchers chanting slogans and carrying signs, others have led to clashes with police who have sometimes used chemical irritants to disperse crowds. Hundreds have been arrested.
