Who is Kimberley Wiilder from Hocus Pocus and what is their importance?

Kimberley Wilder is Jason Wilder's daugher. She attends Tarkington College and agrees to wear an audio recording device so that Jason Wilder can gather evidence of Eugene's "radical" nature. Kimberley does as told, baiting Eugene with highly charged questions which force him to give honest if controversial answers. Later, the audio recordings will be edited in such a way that damns Eugene with distortions. Kimberley is mentally slow and is presented as a willing slave to her father's demands, apparently unaware she is being used by him for political gain.
