OK let me break it down simple enough even you can understand. In their public appearances they claim they have tons of evidence of voter fraud. In the court room when asked, under oath, the same people admitted their claims are all speculative and they have no evidence to back them up. These are the exact opposite statements from each other so either they were lieing on the public appearances, or they were lieing in to the judges. And since there is no befit to them lieing to the judges, in fact there's major repercussions if they do, it's clear which of the two statements they made were lies.
Again, both their televised appearances and their court appearances are public record, look them up for yourself if you still don't believe it. The only reason you have not to is if you purposely want to remain ignorant.
