Defamation. fyi, the term "publish" or "publication" means to spread false information as either orally as slander or in writing as libel.

"Publication" is a term used for both of these. Be careful as to what you say or write. Even privately written slanderous information can be spread.

I was actually surprised recently when a lawyer at a hearing didn't know the definition of publish so it's a normal conclusion to think it means in writing.
