Organizers said they expect even greater numbers for this march in the wake of Trump's immigration crackdown in Minneapolis

A third round of “No Kings” protests is planned this spring, with organizers saying they’ll be the largest demonstrations yet across the United States. Previous protests have drawn millions of people who took to the streets to oppose what they describe as authoritarianism under President Donald Trump.

Edit: this article kind of sucks. Check https://www.fiftyfifty.one/ for some events. I’m sure there are local organizers in whatever area you are in if you search for them. Listed upcoming events on fiftyfifty.one: January 30th: National Shutdown January 31st: ICE Out of Everywhere February 17th: Impeach, Convict, Remove, Defund March 28th: No Kings

Thanks mushroommunk for the extra info and potter297 for calling out the garbage article.
