It is precisely because we know that those people (politicians) are human and likely to do things they shouldn’t or that might not be in our best interest that we want to know before someone gains power of decision or influence what kind of person that person is and what kind of track record is behind that person. It is not trivial information, either the twitter activity of Mr Flynn, nor the possibility that he was on the verge of having a security clearance and was actually participating in the “transition” before having such clearance, despite (or maybe because of?) his evident lack of integrity and prudence when sharing and promoting unsubstantiated “news items”.
Mr Pence avoided answering a simple question. We might have been satisfied with a “Well, everyone on the transition team has to go through certain screenings, one of those being their eligibility for security clearance. Mr Flynn Jr also went through that screening; however, because of the current circumstances, he has been separated from the team and no further screening has taken place. He no longer is participating.” but instead we got a long, involved, evasive answer about his father.
Finally, not answering this simple question in a satisfactory way should lead us to have suspicion on how much information he will keep from us when the question is more complex and of gravity. This behavior on Mr Pence’s part is unacceptable from a person who works for the American people. He must answer all questions in a clear and concise way to the best of his ability. Avoidance means secrets, maybe lies. We’ve already had enough of that. Transparency, please.
