Absence of evidence, is not evidence of absence dude, this is obvious. But fact of the matter is you made an allegation that is not supported by evidence.
If we are talking about what constitutes proof, I can tell what isn't proof ... proof isn't a link from a journal guilty of yellow journalism and of spreading false news, that doesn't cite any credible source, an article written just before the presidential elections from 2014, an obvious hit piece.
Don't link to such junk and I won't pick on you for doing so.
