Yes. But I'd go further. All holders of US political office at all levels should be unable to restrict any conference or interview in which they take part to any single interviewer or news agency, so they cannot control who asks the questions or who airs the event. For several decades, US Presidents have been able to avoid hard questions by cherry picking interviewers or networks in order to "massage their message". That isn't news and it shirks their responsibility to answer hard questions. Tweets are just the next step in the evolution of accountability avoidance. We did away with royal proclamations long ago for damned good reason: you must answer to the people.
