Anybody actually paying atttention knows Trump attacked the WP and owner before
Trump attacks any critics and their owner / advertisers with worse lies and slander he sues others for doing to him. You can't find a more clear blatant hypocrite in office and it only illustrates how little you know when you agree with the man. (not that Trump is wrong 100% of the time but if you don't double check and question him you are an idiot.)
Like any teenager, when you verbally lash out at somebody you try to find some basis in reality to make it hurt more. Trump is fine with outsourcing his highly marked up products and could easily have cut profits to pay Americans while still making a profit. He attacks others using what people want to hear and the little information he has in his senile mind oblivious to contradiction.
