Some Uber employees are frustrated by board member Arianna Huffington's role overseeing the ride-hail giant's internal investigation into sexism allegations, citing her close relationship with CEO Travis Kalanick and recent comments to the media.

Huffington, who joined Uber's board last year, will on Friday afternoon meet with a group of female engineers who plan to raise concerns about whether she can lead an impartial review of the company's workplace practices, particularly after remarks she made on CNN. CNN posted an interview on Monday that quoted Huffington saying sexism was not a "systemic problem" at Uber. On a conference call with reporters on Tuesday, Huffington said she was referring to sexual harassment, rather than sexism broadly, and that CNN had updated its story accordingly. Still, the interview unnerved some Uber employees, who told BuzzFeed News they were already concerned about whether Huffington could help lead an independent investigation into Uber's workplace culture, given her relationship to the company and friendship with Kalanick.

"Everyone is mad with her. There is no way she is independent," one employee told BuzzFeed. "Sexism versus sexual harassment — both are really demoralizing. Her correction doesn't matter. Giving an interview without the investigation finishing was incredibly unprofessional and careless."

Huffington told Uber employees in an email after her call with press Tuesday that "I want to assure you that whether sexism or sexual harassment is a systemic problem at Uber will ultimately be determined by the investigation that Eric Holder and Tammy Albarrán are conducting. And that the board and management team will act upon whatever their investigation finds so that we can create a completely equitable workplace where there is zero tolerance for both sexual harassment and sexism."

"She's on the board. She's qualified. But she needs to be honest about her conflicts here," another employee said. Referring to the interview with CNN, the employee said sexism and sexual harassment could be considered on "the same spectrum," and also noted that it's troubling she made comments while the investigation is ongoing.

"Arianna made this huge fuss over pedantics," the employee said. "Before this, people internally were already definitely worried about her not being impartial."

After Susan Fowler Rigetti published a viral blog post alleging systemic sexism at the ride-hail giant on Feb. 19, Uber hired former attorney general Eric Holder to lead an internal investigation into its workplace environment. Huffington was named to a board subcommittee that will receive and push to implement the results of the investigation, and has become a public face for Uber as it weathers this particular public relations crisis. She appeared alongside Kalanick at the company's first all-hands meeting after the sexism allegations became public.

On a call with reporters on Tuesday, Huffington said the investigation — which is being conducted with the help of Tammy Albarrán, a partner at Holder's law firm — will be "completely thorough, completely independent," and presented to a board subcommittee she sits on. "I am not conducting the investigation," she said. Earlier in the call, Huffington noted that she had spoken to "hundreds of employees either personally or on the phone" in recent weeks.

Several Uber employees told BuzzFeed News that Kalanick's handling of Uber's recent scandals has shaken their confidence in him as a leader, noting that they've been frustrated by his apologies. "I'm extremely unhappy and disappointed in the leadership," said one. Other employees raised an eyebrow over Huffington's recent comments, noting that she publicly described Kalanick as "a close friend" in a post announcing her decision to join Uber's board and told employees at an all-hands meeting that the Uber CEO had been so upset by allegations of sexism at the company that she had to cook him an omelet. (Huffington also referenced making Kalanick an omelet in her "Why I'm Joining Uber's Board" post.) "Glad she is taking precious care of the CEO while there is a serious disconnect going on," one employee said of Huffington.

Huffington declined comment.

This isn't the first time Uber employees have raised concerns about Huffington. In the winter of 2016, sources say, a T-shirt for Huffington's Thrive Global health and wellness company with the slogan "#SLEEPYOURWAYTOTHETOP" sparked outrage among women at Uber, some of whom believed it was available only in women's sizes. A number of Uber employees, complained to Huffington and Uber senior vice president Ryan Graves. The shirt was ultimately removed from the Thrive website.

Reached for comment, Thrive sent BuzzFeed News a screenshot indicating the company also sold the shirt in men's sizes.
