Grossberg says she was made to spy on host Maria Bartiromo, who execs called "crazy" and "menopausal."
Grossberg said Fox executives called Bartiromo names behind the scenes.
One producer, the suit says, called Bartiromo "crazy," "menopausal," and said she often became "hysterical," while another described her as a "diva."
Jerry Andrews, vice president of weekend news at Fox News Media, is also said to have also requested Grossberg spy on the host.
"In February 2022, Mr. Andrews reiterated his directive to Ms. Grossberg to 'keep an eye' on Ms. Bartiromo and report back anything 'crazy' that she said."
