Protesters are gathering nationwide, including Colorado, as President Trump attends a parade commemorating the Army's 250th anniversary on his 79th birthday.

Dozens of Regional Transportation District routes were detoured or delayed throughout metro Denver on Saturday as thousands of Coloradans gathered for “No Kings” protests.

Over two hours after the Denver "No Kings" protest ended, a group of protesters clashed with Denver police officers.

The Denver Police Department advised of road closures near the state capitol due to Saturday's "No Kings" protest.

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.

The organization is made up of EMTs, nurses, and paramedics who will be at the protest, ready to respond to medical emergencies ranging from dehydration and heat stroke to injuries caused by potential police force.

As one of the largest demonstrations of the year prepares to take shape on the steps of the Colorado State Capitol, Denver police are taking to social media to outline what participants can expect.
