David Bonderman resigned from Uber's board on Tuesday after making a sexist comment during a company meeting earlier in the day.
Bonderman, a partner at the private-equity firm TPG, attempted a joke amid a discussion about the steps the ride-hailing company planned to take to address complaints about sexism and gender discrimination in its ranks. He apologized soon after making the statement, which played on a stereotype that women talk too much, but seemed to recognize later that an apology wasn't enough.
"Today at Uber's all-hands meeting, I directed a comment to my colleague and friend Arianna Huffington that was careless, inappropriate, and inexcusable," Bonderman said in a statement. Huffington is a member of Uber's board. "The comment came across in a way that was the opposite of what I intended, but I understand the destructive effect it had, and I take full responsibility for that."
His resignation, first reported by The New York Times, will take effect Wednesday morning.
In a separate statement, Huffington, a fellow Uber board member, thanked Bonderman for stepping down.
"I appreciate David doing the right thing for Uber at this time of critical cultural changes at the company," she said.
Bonderman's departure is only the latest bit of turmoil at Uber. Earlier Tuesday, the company acknowledged that its CEO, Travis Kalanick, would take a leave of absence, and it announced plans to make wide-ranging changes in an attempt to revamp its corporate culture.
Uber has been contending with a series of scandals since a former engineer published a blog post accusing the company of widespread gender discrimination and saying it did nothing in response to her complaints that a manager sexually harassed her.
On Tuesday, Uber released to employees a report put together by former US Attorney General Eric Holder, whose private law firm investigated the company's workplace environment in response to the former engineer's complaints and came up with a list of recommendations for how Uber could improve its culture. The board was discussing those recommendations with employees when Bonderman made his comment.
During the presentation, Huffington announced Wan Ling Martello, a Nestlé executive, would be joining Uber's board, upping the representation of women there.
"There's a lot of data that shows when there's one woman on the board it's much more likely that there will be a second woman on the board," Huffington said, according to a recording of the meeting obtained by Yahoo Finance.
Bonderman responded by saying, "Actually, what it shows is that it's much more likely to be more talking."
