Millions of Americans took to the streets across the country this weekend for the latest No Kings protest. The event happened in cities across Illinois, including Chicago, Springfield, Champaign-Urbana, Belleville, and Carbondale.

We’ll talk about what happened this weekend, and put No Kings in the larger context of American history. Our guest is civil rights lawyer Gloria J. Browne-Marshall, whose new book is “A Protest History of the United States.”

Today on The 21st: we talk to a scholar about the long history of violent protest in America, we ask if it's safe to go to the dentist, and we dry out from another month of record rainfall.

Students from eight high schools in the Champaign-Urbana area will stage a demonstration Saturday to call for stronger gun control measures. The protest is one of hundreds of similar events happening across the country, including Washington D.C., under the moniker “March For Our Lives.”

The University of Illinois College of Law Dean says people who protested the visit of the U.S., Deputy Solicitor General protested the wrong person.

Students at Parkland Community College rallied in support of a student arrested earlier this month, saying police and administrators are "persecuting" black students and teachers.
