I've also been looking for this. The "insurrection" over shadowed it. Interestingly I watched the last stream of the girl shot in the neck (forgive me for not having her name at the tips of my old fingers) and she said in that stream that she had heard from the park service that over 3 million were there for Trump's event. Take that for what you will. I would also love to have seen an overhead view of that crowd that morning.
