No, libel is a published false statement that is damaging to a person's reputation; a written defamation. Slander is spoken. We're talking about Libel, so it's the written articles that have been defaming DJT and his family. Think Washington Post, Think NYT. Think MSNBC, CNN, ABC, CBS, NBC written articles.
