Margaret Brennan is normally good at hard hitting questioning. In this am case regarding Corona Virus, her "hard" hitting was unnecessary and her body language was terrible. Getting the facts and the info is important. However, journalists should do this in a way that soothes rather than incites the concerns of the public.
In trying to be the best/toughest you did your viewing public and your guests a disservice. Thank goodness the guests answered reasonably, calmly and correctly.
Margaret, not only should you be ashamed, you should apologize.
