That just goes to show how many people don't understand the First Amendment.
Gives people the right to print almost anything, no matter how factually challenged it is - as long as it just skims the asymptote that is slander/libel.
Conversely, it also gives people the right to ignore any media outlet that lowers itself to the sleazy level of Penn Live and for people to call a rag a rag.
As for "access" to public officials...well, there is a danger it could always reach Trumpian levels and reporters are denied access for printing TRUE things that a politician doesn't like - because, you know, the truth hurts sometimes. But jeez, now that every yahoo with a keyboard and a blog can call themselves a journalist...it stands to reason that you can't give credentials and access to everybody. If a politician fills the room with sycophants, people will notice. If a politician bans some rag like PennLive, then the wisdom of the decision ultimately lies with how many people agree with his notion that PennLive IS a rag. In this case, the guy might be thin-skinned...but PennLive is most assuredly a haven for sludge.
