PV went on the record saying this girl was Not the leaker and that their LEAKER remains on the inside of ABC.
The girl’s job at the time was to clip on-mic moments, for antics and hilarity, to possibly used later for fun, or whatever reason, in a subsequent news cast.
The girl clipped it and it was viewed by the editing room full of others, some who chattered about it and videoed the clip, presumably on their cell phones, etc.
One of them leaked it, but the girl had already heard it LIVE, and therefore claims she never viewed it again, once she had clipped it.
Thank you Rita, that clears it up!
