The only thing new about Trump's attacks on the media is that he does it himself instead of delegating that job to his underlings the way Nixon did with Agnew.  It's malignant if a president hated by the beltway establishment attacks media outlets they see as respectable, but I doubt Bernstein saw a problem with Clinton suggesting talk radio was complicit in the Oklahoma City bombing or having his aides call Matt Drudge "Rat Sludge."
