Thousands of Idahoans flocked to downtown Boise amid national "No Kings" protests Saturday against President Donald Trump and his administration. Protesters filled the Capitol steps and lawn, and spilled onto nearby streets with anti-Trump signs and chants in the unforgiving heat.

Waving American flags and carrying homemade signs, thousands of people took part in a “No Kings Day” protest Saturday at the Idaho State Capitol.

Organizers of "No Kings" protests have scheduled demonstrations in more than a dozen cities across the Gem State to coincide with what they describe as an expensive display of presidential power. The coordinated protests target what organizers call government overreach under the Trump administration.

Organizers of the “No Kings” demonstrations said millions had marched in hundreds of events. In Oregon, tens of thousands of people gathered in downtown Portland for two large protests -- one that began in Tom McCall Waterfront Park and the other at the Oregon Convention Center.

Around 2,000 protests were planned on Saturday in opposition to President Donald Trump. Large crowds turned out in cities like Portland, Denver, Chicago, Houston and Los Angeles – and in smaller communities in traditionally conservative areas.

Hours after the Boise rally brought thousands to the Idaho State Capitol, Nampa’s own “No Kings” rally brought hundreds of the city’s residents to Nampa City Hall.

No Kings protests took place across the country from New York City to Atlanta to Los Angeles. The 50502 Movement, which stands for 50 states, 50 protests, one movement, said the nationwide protests are aimed at calling attention to what they say are authoritarian actions of the Trump administration.

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