Considering their lying corrupt past behavior & extreme efforts to contort/ignore the law regarding crimes by Hilly, I’d say their refusal to confirm/deny is the same as a confirmation in my way of looking at it. Can’t trust a thing they say any more.
In MEDIA CIRCLES it is known as a NON-DENIAL DENIAL.
Non-denial denial
From Wikipedia, the free encyclopedia
A non-denial denial is a statement that, at first hearing, seems a direct, clearcut and unambiguous denial of some alleged accusation, but on carefully parsing turns out not to be a denial at all, and is thus not explicitly untruthful if the allegation is in fact correct. It is a case in which words that are literally true are used to convey a false impression; analysis of whether or when such behavior constitutes lying is a long-standing issue in ethics. London's newspaper The Sunday Times has defined it as "an on-the-record statement, usually made by a politician, repudiating a journalist's story, but in such a way as to leave open the possibility that it is actually true".
