"Already, he has said he wants to “open up” libel laws so that people like him can more easily sue newspapers."  

Actually, what he wants to do is kill New York Times V. Sullivan which allows newspapers to lie about 'public figures' in this country and not be sued for libel because they are 'public figures'.

Oddly enough, the other muck-raking newspapers in say, Great Britain, don't have this Judge-made rule and wind up having to pay performers, actors and and other 'public figures' millions when they are found to have libeled them.   

Kathleen and her co-journalists are probably safe to continue to lie; NY Times v. Sullivan has been around a long time now.
