I certainly understand what you may want to say, OK, but Trump is president now, not a candidate anymore. He should take a first step to withdraw his fight with media. But this fighting media has become part of his winning formula. Why will he give up? He thinks it is still working for him. Of course he won't give up the fight before media give up the fight.
