Activists in Denver are joining a nationwide protest against President Donald Trump outside the Colorado state Capitol on Saturday, beginning with an “activist fair” at Lincoln Veterans Park before thousands are expected to march downtown.

“The Activist Fair is a celebration of community and solidarity, showing Trump that we’re not scared, we’re not depressed, and we sure as hell aren’t giving up,” the Denver “No Kings” event organizers said in an invitation.

The activists are primarily protesting Trump’s crackdown on illegal immigration, notably his decision to deploy federal agents to arrest and deport people illegally staying in the country. Trump had campaign on the promise of curbing border crossings and deporting people convicted or accused of violent crimes. 

The White House said in the first 100 days under Trump, daily border encounters went down by 93%, while encounters with “gotaways” — which the administration called the “the top threat to public safety” — dipped by 95%. His administration also reduced immigrant crossings by 99.99%, the White House said. 

In Denver, the “activist fair” will feature an aid station, seminars, music and games, said organizers, who insisted that protesters remain peaceful. 

The protest is planned between noon and 4 p.m. at Lincoln Veterans Memorial Park, located between the west steps of the Colorado state Capitol building and east of Civic Center Park.

After the “fair,” protesters expect to cross the street and head for the state Capitol, according to organizers.

Denver Police Department officials said they are aware of the planned protest and will become involved if safety issues arise.

“DPD will monitor any demonstrations and have resources available to respond, if necessary, to address any safety issues,” a spokesperson told The Denver Gazette.

“The department respects people’s right to demonstrate and encourage demonstrations to be conducted in a safe and lawful manner,” the spokesperson said, adding temporary road closures “could occur as the demonstration evolves.”

Last Tuesday, at least 18 people were arrested for protests in Denver, according to the Denver Police Department. The arrested individuals were apprehended on suspicion of a variety of charges, including assault, interference with a police officer, criminal mischief, failure to obey a lawful order and obstruction of streets, the department said.

Some other Colorado cities joining in on protests include Parker, Castle Rock, Colorado Springs and Fort Collins.

Parker town officials sought but failed to persuade organizers to reschedule their protest, which is happening at the same time as the popular Parker Days Festival. The festival began Thursday and will run through Sunday.
