I commented on the article you provided. It simply lacks detail to provide condemnation. If you can provide a specific incident with a specific lie that is disproven with specific evidence. I am happy to provide comment and if need be condemnation.
What I think you'll find is you have developed confirmation bias that you think he is a liar, therefor you are perceiving conjecture as evidence of lies. Yet the conjecture has little to no evidence to support the accusation.
