Last week, Fox News announced that longtime host Kimberly Guilfoyle, who is dating Donald Trump Jr., would be leaving the network. Some Fox News and White House insiders were surprised that she was choosing to move on from the cable news channel and head to a pro-Donald Trump super PAC. Well, a new report just revealed the reason for her surprising move.

Guilfoyle’s departure was initially billed as her decision. However, according to the Huffington Post, she did not leave the network voluntarily.

Sources told HuffPost that Guilfoyle was informed her time at Fox News was up following a human resources investigation into allegations of inappropriate behavior including sexual misconduct, and that her lawyers had been involved since the spring.

She was accused of engaging in emotionally abusive behavior and showing colleagues personal photos of male genitalia.

Sources also said that despite being told she would have to leave by July, Guilfoyle repeatedly attempted to delay her exit and tried to have her allies appeal to Rupert Murdoch, the executive chairman of 21st Century Fox, the parent company of Fox News, to let her stay at the network.

Multiple sources told HuffPost that Guilfoyle’s exit from Fox News, where she had worked since 2006, came after her alleged inappropriate workplace behavior could no longer be tolerated by the network.

Guilfoyle announced Tuesday that she had left Fox News. ShareTweet
