The President says polls he dislikes are fake, that the media publishing them is crooked, and that the FCC will ride to the rescue. No poll, outlet, or number is named, and the phrase “something must be done about it” is left to do its own work.
The post does not explain what the FCC would actually do. The agency licenses broadcasters and regulates spectrum; it does not audit survey methodology, and the First Amendment is generally understood to cover the publication of numbers the President finds unflattering.
