Dropping the mike is working for President Trump and Kayleigh McEnany.
The press is being more respectful and asking serious questions without the accusatory tone.
They are realizing or are being TOLD to realize that such antics bring a rapid END to press conferences.
It's not so much that but when they use their follow-up question to argue and call the President a liar as one did on Saturday ("that is false information), POTUS says "thank you" and turns and leaves.
