Protesters flooded into streets chanting, marching and waving homemade signs. Organizers said nearly 7 million people showed up for the demonstrations across the country.

Nationwide "No Kings" protests on Oct. 18 will target President Donald Trump's immigration policies and deportation operations in major U.S. cities.

In June, millions of activists across the U.S. gathered for “No Kings” protests in all 50 states, in what was called a “nationwide day of defiance.” Their message? The United States doesn’t have kings – and people need to remind the current administration that public officials hold office to serve the public and not themselves.
