You can’t do this with impunity in the UK or Canada or Australia. The First Amendment doesn’t sanction this. The new FCC should fine and suspend these untruth tellers as well as penalizing their owners and yanking their licenses if they don’t put a stop to it. Their online rights also should be limited. It may be too late to bring back the Fairness Doctrine but not too late to punish those willfully and knowingly using “ airwaves” for spreading lies and misinformation.
