The information was released after a report by Variety last month regarding allegations that he had abused his female coworkers throughout his time there.
Lemon penned, "I am stunned. "I would have thought that someone in management would have had the decency to tell me directly after 17 years at CNN."
CNN disputed Lemon's report in a tweet, calling it "inaccurate." He was given the opportunity to speak with management,
according to the network, but "instead released a statement on Twitter."
According to a memo given to NBC News on Monday, CNN CEO Chris Licht stated that the network and Lemon have "parted ways."
