AKIPRESS.COM - In the midst of announcing the findings from a sweeping sexual harassment investigation, a board member made a joke about gender stereotypes, adding even more fuel to claims of a toxic culture, CNN reported.

On Tuesday afternoon, investor David Bonderman, a member of Uber's board, said having more women on the board would just lead to more talking, according to leaked audio obtained by Yahoo Finance. On Tuesday night, he announced in a statement that he was resigning from the board, calling his comment "careless, inappropriate and inexcusable."

It's the latest hit for the company. Earlier Tuesday, CEO Travis Kalanick said he was taking an indefinite leave of absence to grieve the death of his mother. On Monday, senior executive Emil Michael announced that he was resigning. Michael was Kalanick's No. 2, and both men had been mentioned alongside multiple scandals recently.

Michael visited an escort bar in South Korea with Kalanick and other employees in 2014. He was also reported to have been one of the executives who viewed medical records of a woman who had been raped by an Uber driver in New Delhi.

Last week, 20 people were fired after a separate investigation into harassment at Uber.
