She worked in the Trump WH and was an election denier, but she did concede. Interestingly, so far the deniers have been conceding when they've lost, which they mostly have. I wonder if it's that they've seen it's not a great winning message, so have gotten the hint to give it up. Or maybe they're fearful of the legal consequences that some deniers have received. Whatever the reason, it is a relief that they are both losing and conceding.
One of the loudest deniers, Kari Lake, though is still in contention in her race.
