What is so hard about banning fake news? If an organization or person dliberately publishes information they know to be false make it a serious felony. Who gets to decide if they were deliberate? Judge or jury like any prosecution. Who gets prosecuted? Anyone against which the prosecutor can prove their false information publication was deliberate. For example, if a request is made to them to correct false information and they acknowledge it is false or refuse to provide independently verifiable information to back up their claims then prosecute them. If they have confidential sources, they should be forced to disclose all information that isn't personally identifiable and if that is refused or is false then you have them or providing false info and obstructing justice.
