Thousands gather for Nashville's "No Kings" protest as ICE reports record detention numbers. Demonstrators voice concerns about constitutional rights and immigration policies.

The organizers of this weekend's upcoming "No Kings" protests have issued a video reminding people about the event. The video, released on the No Kings website, reminds those planning to attend of details and calls on people to join the protests.

Around 2,000 protests and rallies were planned nationwide, with thousands of people also attending staged “No Kings” events in Manitowoc, Sheboygan and Green Bay. Rallies were canceled in Minnesota out of caution following shootings targeting local lawmakers.

Opponents of President Donald Trump's administration on Saturday rallied in nearly 2,000 locations across the country, with thousands demonstrating in Northern California.

Organizers across the country named the mobilization “No Kings.” The rallies were organized in opposition to a military parade in Washington, D.C. on the president’s 79th birthday Saturday. The parade is happening on Flag Day, which also marks the U.S. Army’s 250th anniversary this year.

We heard they had 1,300 signups. We’re guessing there are going to be maybe 2,000 today,” said volunteer Lauren Reynolds.

Millions marched in cities and towns across the U.S. in "No Kings" protests to rally against the Trump administration.

While President Donald Trump attended a military parade he ordered on his birthday to recognize the 250th anniversary of the U.S. Army in Washington, D.C., thousands of people in the Kansas City metro area flexed their First Amendment right Saturday to voice their opposition to polices of the Trump administration during the “No Kings” national day of defiance.
