Protesters took to the streets and marched through downtown Denver on Saturday, June 14, 2025, joining nationwide protests against President Donald Trump’s policies.

More than a dozen rallies across the state were peace. Police used pepper balls and smoke on one group in Denver.

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.
