Bernstein is sucha piece of excrement . Trump is reacting to  the BS that the Bernsteins of the world are throwing at him. Journalism died with the election of Barack Obama. Now the media are at war, trying to destroy him with no need for the truth to ever pass their lips. They still don't realize they are attacking a street fighter, who is not going to sit there and let them get away with all the lies and ad hominem attacks on him, his family, and his supporters without him hitting back. Trump has never done a single mean tweet to anyone who has not disparaged him first.
