@coldjoint,
I previously said there is no widespread fraud. I agree with what Barr said,: "To date, we have not seen fraud on a scale that could have affected a different outcome in the election".
The statement implies there is certainly voter fraud, but it is in such a much smaller scale that an investigation would not change the winner of the election. Even if any fraudulent ballots are thrown out, the outcome would remain the same: Biden won.
