Don Lemon filed a report with the NYPD on Wednesday after receiving a series of racist death threats on Twitter.
Lemon filed a report for aggravated harassment after he claims he was sent numerous "threatening and anti-black messages" via Twitter.
Police say no arrests have been made and the investigation is ongoing.
According to reports, the alleged harasser's Twitter handle and profile make it clear he's an ardent supporter of President Donald Trump. Lemon has been an outspoken critic of Trump, lambasting him for his reaction to the events in Charlottesville and for the way he handled a phone call to the widow of a soldier killed in action.
