Unfortunately for Trump, the courts have consistently sided with the press when they report accurate and factual statements, even if they may be unflattering. This doesn't seem to register with Trump. If asked to define what "treating me fairly" actually, genuinely means, I'm pretty sure he couldn't.
Do you think the media needs to be a little more accountable or the hysteria is good?
Practically I don't think Trump would get very far with any sort of libel lawsuits. Even in Italy, Berlusconi's "sue into silence" strategy was not 100% effective -- and Berlusconi is a much more dominant player in comparative national medias than Trump is.
Even so, my gut feeling is that Trump would be perfectly okay with a Putin / Erdogan style strongman media takeover if he could get away with it.
Berlusconi was nowhere near Erdogan's style of strongman politics, but unfortunately, during his term, Berlusconi did stifle press freedom somewhat in Italy... primarily via questionable libel lawsuits against any critical outlet if I recall.
It's easy for me to see Donald Trump following a similar pattern, of attempting to sue any critical outlet into silence.
