It is rare for any politician to answer every single question from the press.  Trump actually did answer them, just not in a way that some would want him to.

Sometimes,  say 'nobody cares about this but you", at other times they say "maybe asking silly things noone wants to know is why your ratings are so terrible".  Or they could talk about that Monty Python dead parrot skit to explain that the american people already moved past that and that a dead parrot is in the end just a dead parrot.

It's mean to say so, but as long as reporters are not jailed, it's doubtful to see how mocking them rightly or wrongly as irrelevant violates the bill of rights for reporters.
