Here is what I heard reported about whistleblowers to Congress:
The Person in charge of the detail was a woman known by the Trump team to be incapable and incompetent before the event ( presumably from failures at prior events ). The team was horrified to learn she would be in charge at this open air event, but there was nothing they could do to change it ( again presumably, the woman was a DEI hire ).
She is still working security and has not been fired or as far as anyone knows, questioned.
Do we have a name.?
