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

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

The "No Kings" protest set for Saturday is poised to be the largest local demonstration against President Trump. The question is: Are Mayor Mike Johnston and the Denver Police Department prepared? Why it matters: Any civil unrest will reveal what Denver has — or hasn't — learned from the mistakes some officers made during the George Floyd protests five years ago.

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.

Northern Colorado saw some of the state’s biggest protests Saturday, but even smaller communities drew crowds.

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

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.

Millions to attend nonviolent protests against Donald Trump, his military birthday parade, and the crackdown on dissent in Los Angeles.
