A CBS News journalist was detained and charged with resisting arrest during a clash between protesters and supporters at a canceled Donald Trump rally in Chicago. Sopan Deb, who has been covering Trump for the network since the real estate mogul launched his candidacy, kept filming when he was detained.

In the video, Deb can clearly be heard identifying himself as a credentialed journalist as he was being handcuffed. “I have press credentials I can show you,” he says. But those arresting him don’t seem too interested. The video taken at the scene does not ever show Deb resisting arrest, as authorities claim.

David Rhodes, the president of CBS News, mentioned the arrest on Twitter and defended the journalist. “.@SopanDeb was handcuffed, later charged with resisting arrest; on tape you see he did not resist, identified himself as working press,” Rhodes wrote.

Deb also took to Twitter as chaos erupted at the Trump rally: “I’ve never seen anything like what I’m witnessing in my life.”
