David A. Logan, professor of law and former dean of the RWU School of Law, who has studied and written extensively about First Amendment issues:
Among President-elect Donald Trump's many ill-informed campaign statements was that he was "going to open up libel laws."
Where to begin? First, libel law was, and remains, state law. Second, while federal legislation does impact pockets of libel law (most notably, the Communications Decency Act protects websites from liability for merely hosting defamatory statements posted by third parties), the primary reason why politicians have trouble winning libel actions is not federal statutes but rather the First Amendment.
