"[Mark ]Zuckerberg claimed that new limits on what’s posted on social media would be to “pull back on free expression.”  This is utter nonsense.  The First Amendment says that “Congress shall make no law” abridging freedom of speech, however, this does not apply to private businesses like Facebook.  We’re not asking these companies to determine the boundaries of free speech across society.  We just want them to be responsible on their platforms."

Facebook already has "Community Standards" which it still needs to enforce more than it does enforce them, by the way. So, why isn't Facebook being responsible by its own standards?
