RSBN interviewed Kate Mazzochetti on their livestream: [1:25:50 - 1:27:20]
she was admitted into the arena, but not given "VIP" access behind the podium. After POTUS leaves the stage you are free to walk around the arena and take a "selfie" from those seats though (notice all the empty seats - the rally is over)
that's a rabbit-hole I'd rather not enter
kindly disregard the voices in your head
