Here we have the absurd situation of the governor of Kansas - Sam Brownback - pressuring a school to discipline a student over a nasty tweet she made about him (though he is now blaming underlings for this foul-up). Even more absurdly, the first instinct of the school adminstrators was to comply, and try to get the student to write an apology letter!
What on earth were they thinking? Isn't this an obvious abuse of political power to try to control people's speech about a public figure?
In the end, it's the politician who has had to apologise for his intrusive and illiberal actions (or those of his staff, if you want to give him the benefit of the doubt on that aspect). And rightly so.
