Mckesson accused Pirro of defamation over an appearance she made on "Fox & Friends" in September of 2017.
"In this particular case Deray Mckesson, the organizer actually was directing people, directing the violence," said the Fox News personality, as reported by The Blaze. "You've got a police officer who was injured, he was injured at the direction of DeRay Mckesson."
The Black Lives Matter leader organized the protest in Baton Rouge, Louisiana, where the officer Pirro referenced was injured.
Following the segment, Mckesson tagged the judge in a video clip of her commentary. "I was found not guilty & I didn't direct any violence. In fact, I was protesting the violence of the police," the activist wrote, referencing a failed lawsuit aimed at him and the Black Lives Matter movement. "Stop lying."
