The biggest single-day mobilization of resistance since President Donald Trump returned to office is expected Saturday, June 14, with "No Kings" protests in cities across the U.S.

The parade was the spectacle event Trump had long wanted. It also helped sparked the largest mass opposition to him since his inauguration 145 days earlier.

More than 1,000 demonstrators are expected to rally in West Palm Beach today for 'No Kings Day,' a nationwide event protesting Donald Trump on his birthday.

Organizers are calling for Americans to attend demonstrations across the country to protest President Trump on his 79th birthday.

Coordinated "No Kings" protests are underway from coast-to-coast, part of a "national day of peaceful protest" against the Trump administration that is expected to draw millions. Protesters in some areas braved wet weather to raise signs and chant slogans supporting the rights of immigrants and criticizing what they see as Trump's power grab.
