Donald Trump Jr and Kimberly Guilfoyle

Journalist Kimberly Guilfoyle was under investigation for alleged sexual misconduct before Fox News’ security escorted her out of the Fox studios last week.

Guilfoyle, who is dating President Donald Trump’s eldest son, Donald Jr., left the news channel to join a pro-Donald Trump PAC, short for political action committee.

According to the Huffington Post, there were rumors that Guilfoyle was under investigation for misconduct long before she announced she might join the Trump administration (possibly replacing Sarah Huckabee Sanders).

It was initially reported that Guilfoyle made the decision to leave Fox. But sources tell the Huffington Post that Guilfoyle was told she would be fired after an investigation into disturbing misconduct.

Guilfoyle, who was assumed to be “untouchable” due to her close ties with former Fox News chairman Roger Ailes, allegedly attempted to appeal to the higher ups to keep her job.

Guilfoyle said that, as a single mother, she had to consider her son’s financial future and couldn’t afford to leave the high-paying gig, multiple sources told HuffPost.

The Daily Beast reported that Fox News staff waged a “whisper campaign” against Guilfoyle, who allegedly used hair stylists for her own personal outings.

But more serious allegations against Guilfoyle soon surfaced.

via MSN — Six sources said Guilfoyle’s behavior included showing personal photographs of male genitalia to colleagues (and identifying whose genitals they were), regularly discussing sexual matters at work and engaging in emotionally abusive behavior toward hair and makeup artists and support staff.

Two years ago, network insiders considered the idea of Guilfoyle’s involuntary departure from Fox News to be impossible. She was a protégé of Roger Ailes, who was the chairman of the network at the time, and many saw her as untouchable. She was, as one source described it, “the woman who knows too much.”
