The AG is pandering to the Trump base that has no idea what the First Amendment is or what it does.  Free speech does not mean that anyone can say what they want without others reacting or counter protesting.  It only means that in most cases, the speaker cannot be arrested.  The restraint provided only applies to the government - not any individual or group of individuals.
