It is a measure of President Trump's thin skin and personal immaturity that he hits back in such a cavalier way when he feels himself under personal attack - an entirely new experience for him, but one he needs to get used to now he is operating in the real world, and not his empire bubble.
He referred to Meryl Streep as a 'mediocre actress' which is petty, small-minded, and given Ms. Streep's level of professional awards, clearly inaccurate.
Now he refers to a 'so-called judge ...' - it's time his 'people' muzzled this childish need to belittle people who cross him, it's utterly undignified, and it is completely inappropriate for the President to whine and stamp his feet in this way.
This man is the President, - will someone please tell him that he is required to act with levels of dignity and restraint that he neither possesses, or shows any signs soon of acquiring.
