Firstly, it cant be slander as that only applies to verbal communication. Secondly, if you read the article they refer to him as a predator based on these allegations. They are reporting these allegations af if they are facts. At this point it is just defamation, but if it goes to court and we find out there isnt a case then it becomes slander. Theres no way someone can call someone a derogatory term in good faith.
