Mark Zuckerberg is in the news again but this time it isn’t about Facebook. Like any billionaire, Zuckerberg and his family are surrounded by security guards 24/7. But unlike most billionaires, Zuck’s head of security, Liam Booth, is accused of racist and sexual remarks against his wife Priscilla Chan and other staff members, according to NBC. Booth, a former Secret Service agent, has been placed on leave while the investigation into his behavior is ongoing.

According to The Verge, Booth allegedly made racist and sexist remarks on various topics. He allegedly made a remark about Chan’s ethnicity and her driving skills. “She’s a woman and Asian, and Asians have no peripheral vision,” he said while pulling his eyes back, according to CNET. Furthermore, Booth allegedly said that he “didn’t trust black people” even though he had worked for Barack Obama. He is also alleged to have made a remark about Black Lives Matter. “White Lives matter more than black lives,” he said.

One former staffer accused Booth of harassing a gay man who was part of Zuckerberg’s staff and groping the man at a Nobu restaurant last year. She also claimed that Booth sexually harassed her by having other staffers tell her to change clothing because it was distracting. Additionally, she claimed that she was fired for “rolling her eyes in a meeting” and for complaining about a negative write up.

Another former staffer claimed Booth demeaned a transgender staff member by using the word “it” to describe the person instead of the preferred pronoun.

Booth has allegedly commented about Priscilla Chan and Mark Zuckerberg’s philanthropy organization, the “Chan Zuckerberg Initiative” for their diversity efforts.

The former staffers said that they issued multiple complaints to Brian Mosteller, the managing director of Zuckerberg’s private office. However, they claimed that Mosteller failed to take action. Two former staffers are asking for compensation for emotional distress and lost wages.

“The family office takes complaints of workplace misconduct very seriously and our human resources team promptly investigates all such matters,” Ben LaBolt, the spokesman for the Chan Zuckerberg family office, told Business Insider. “The allegations against Liam Booth were brought to the office’s attention for the first time by The Bloom Firm after both employees had left employment by the family office and engaged legal counsel. As soon as The Bloom Firm presented these allegations,the family office engaged Munger, Tolles & Olson, an outside law firm, to conduct an investigation of all allegations made by The Bloom Form to determine whether the claims have merit. The investigation is ongoing. Mr. Booth is on administrative leave pending the completion of this investigation.”

Mark and Priscilla did not know about Liam Booth’s behavior before the investigation.
