If they ever started to ask for professional standards to be met by CNN, etc. it would call for a full turnover of the staff.
Like my earlier joke (hopefully funnier like wine with age):
Sarah Sanders demands WH briefings, to be cleared of any self-serving, prima donna,arrogant,spotlight seeking, unprofessional, biased , interrupting journalists.
Next session:
Sarah: Hello. Hello, is anybody out there?
Holding but one a week, at 4:00 PM on Fridays would likely have a similar effect.
