They wont release ANY of the reports and most likely there isnt any because the Son of a B*tch that shot her was most likely a congressman. A black congressman.
I’m only speculating but it wouldn’t surprise me if the crowd got too close to congressional leadership or even the VP. It was revealed later that Pence never left the Capitol building IIRC.
One can argue that the shooting was not justified, but I am not surprised the shooting happened.
