the apparent last straw was "oh, and she's a slut", showing her having sex with Josh. Aside from the obviously egregious invasion of privacy, it's that whole thing of only needing to use a woman's sexuality against her to invalidate all the work she's done. "Yeah she's a lawyer and this and that BUT SHE *****, YO, HOW DARE SHE", and it often works. Nothing to say about their work, etc, and why go to the effort of digging up actual dirt when you can just flex these dumbass gender norms and get the same result.
The Philippines' previous administration had this as one of the first things on their to-do list: to silence an incumbent female senator who was a vocal critic of that administration, they spun this whole tale of how she had a sex tape with some dude. Same administration run by a creature who made casual rape jokes on a weekly basis.
