'No Kings' protests draw millions. Can they turn momentum into change?

With crowd numbers estimated at several million in more than 3,000 locations, the No Kings Day protests on March 28 – animated by opposition to President Donald Trump – might turn out to be the largest combined single-day protest in U.S. history.

The movement, which bills itself as "rising against [Mr. Trump's] authoritarian power grabs," cites, in part, his administration's immigration enforcement tactics and the Iran war.

Staysi and Caleb Lougheed, who commuted to Washington from Pennsylvania and joined a march from Arlington National Cemetery to the Washington Monument, say showing up matters.
