An estimated 8 million people in the United States participated in “No Kings” protests against President Donald Trump on Saturday, organizers say, as Americans vented their frustrations on his leadership.

“At least 8 million people gathered today at more than 3,300 events across all 50 states,” No Kings says in a press release. US authorities have not provided an official count on the number of participants in Saturday’s events.

According to the organizers, there were about one million more participants and 600 more events compared to the last No Kings demonstrations in October.
