 Uber CEO Travis Kalanick announced the move in a letter sent around to company employees which was seen by ABC News. 
 
 The announcement came a day after Kalanick vowed to immediately investigate the allegations contained in a long blog post written Sunday by Susan Fowler, who said that she faced sexual harassment while working as a site reliability engineer at the ride-hailing technology company from November 2015 to December 2016, and that her complaints to management had gone unheeded. 
 
 In his note to employees, Kalanick said he hired Eric Holder, Attorney General under President Barack Obama, and Tammy Albarran -- who are both partners at the Washington D.C.-based law firm Covington & Burling -- to "conduct an independent review" of Fowler's claims. 
 
 "I believe in creating a workplace where a deep sense of justice underpins everything we do," Kalanick said in the memo. "What is driving me through all this is a determination that we take what’s happened as an opportunity to heal wounds of the past and set a new standard for justice in the workplace." 
 
 The company plans to hold an "all hands" meeting on Tuesday to "discuss what’s happened and next steps," Kalanick's note said. 
 
 Fowler, who currently works for the online payments provider Stripe, wrote in her Sunday blog post that a manager of hers when she worked at Uber had sexually harassed her over online chats. She wrote that after she took screenshots of the conversation and sent them on to HR, no action was taken. 
 
 “Upper management told me that he ‘was a high performer’ (i.e. had stellar performance reviews from his superiors) and they wouldn’t feel comfortable punishing him for what was probably just an innocent mistake on his part," Fowler wrote. 
 
 Kalanick on Sunday called the descriptions in Fowler's post "abhorrent," saying that the actions described have no place at Uber. 
 
 "I have just read Susan Fowler's blog," he said in the Sunday statement. "What she describes is abhorrent and against everything Uber stands for and believes in." 
 
 "It's the first time this has come to my attention so I have instructed Liane Hornsey our new Chief Human Resources Officer to conduct an urgent investigation into these allegations," he added. "We seek to make Uber a just workplace for everyone and there can be absolutely no place for this kind of behavior at Uber -- and anyone who behaves this way or thinks this is OK will be fired." 
 
 Kalanick also posted his reactions to Twitter on Sunday, embedding a link to Fowler’s blog post.

 Uber board member and Thrive Global CEO Arianna Huffington also promised a “full investigation” on Sunday and asked people to email her directly about the allegations. 
 
 According to Monday's memo, Huffington, along with the company's human resources chief, will attend the "all hands" meeting on Tuesday and will conduct "group and one-on-one listening sessions" to get feedback from employees. 
 
 ABC News could not independently verify the details of Fowler’s story. ||||| Uber has hired the former US attorney general Eric Holder to investigate allegations of sexual harassment after an engineer went public with claims that she repeatedly faced sexism and discrimination at the ride-sharing company. 
 
 In a staff email shared with the Guardian on Monday, Uber’s CEO, Travis Kalanick, said Holder would conduct an “independent review” and also revealed that women made up only 15% of the company’s workforce in engineering, product management and scientist roles.

 The hiring of Holder, who was attorney general under Barack Obama, comes as the description of harassment from Susan Fowler, a former site reliability engineer, has gone viral, prompting women across Silicon Valley to share stories of facing misconduct and discrimination in the male-dominated tech industry. 
 
 “It’s been a tough 24 hours. I know the company is hurting,” Kalanick said in his email. “It is my number one priority that we come through this a better organization where we live our values and fight for and support those who experience injustice.” 
 
 Fowler’s lengthy account on her blog alleged that management and the HR department at the San Francisco-based company frequently dismissed documented cases of sexual harassment, protected a repeat offender and threatened to fire her for raising concerns. 
 
 Fowler, who declined to comment further on Monday, alleged in her post that a manager immediately propositioned her for sex when she joined in late 2015, and that a director explained the dwindling number of women in her organization by saying “the women of Uber just needed to step up and be better engineers”. 
 
 Fowler, who now works for technology company Stripe, said a manager harassed her with messages on the company chat system but did not face any consequences from HR despite her providing screenshots. She said she later learned that other women had complained about his inappropriate behavior. 
 
 “Upper management told me that he ‘was a high performer’ … and they wouldn’t feel comfortable punishing him for what was probably just an innocent mistake,” she wrote.

 In one anecdote, she said managers had promised staff leather jackets but ultimately decided not to order them for women “because there were not enough women in the organization to justify placing an order”. 
 
 
 
 Following her complaint about that incident, an HR representative asked “if I had ever considered that I might be the problem”, she said. Her manager also later told her she was on “thin ice” and that if she filed another report, she would be fired, according to her account. Although an HR official admitted that this threat was illegal, no action was taken, she said. 
 
 On Monday, Kalanick said Uber board member Arianna Huffington, founder of Huffington Post, would also assist in the investigation alongside Liane Hornsey, the company’s newly hired chief human resources officer, and Angela Padilla, general counsel. 
 
 The harassment controversy comes as Kalanick struggles to move past the viral #DeleteUber campaign, which stemmed from his participation on Donald Trump’s economic advisory council. 
 
 The company has long refused to release demographic data on its workforce, even though most major tech companies have in recent years begun disclosing data and publicly acknowledging their lack of diversity. Apple, Facebook, Google and Twitter have all published staffing reports. 
 
 Kalanick’s email only provided gender data, saying the 15% figure for women “has not changed substantively in the last year”. The email did not offer statistics on the number of women in senior roles, a key metric for diversity. 
 
 A spokeswoman declined to provide racial demographic data to the Guardian on Monday. The CEO said he and Hornsey would publish a “broader diversity report” in the coming months. 
 
 Fowler alleged that when she left Uber at the end of 2016, out of over 150 engineers in the site reliability engineering teams, only 3% were women. 
 
 This is not the first time a tech corporation has hired Holder in the wake of a discrimination scandal. In 2016, home-sharing startup Airbnb brought him in to investigate claims that users were refusing to rent their homes to black guests, a controversy that spread under the hashtag #AirbnbWhileBlack. The company subsequently implemented new staff and rules aimed at preventing discrimination, though some critics said the reforms were inadequate.
– Eric Holder isn't just preparing to fight President Trump's administration on behalf of California. He's also heading what Uber CEO Travis Kalanick calls an "urgent investigation" into claims that the ride-sharing service discriminated against a female engineer while ignoring her complaints of sexism and harassment, reports the Guardian. In a Monday email sent after "a tough 24 hours" for the company, Kalanick says Uber has hired Holder and a colleague at law firm Covington & Burling to conduct an "independent review," adding it's "an opportunity to heal wounds of the past and set a new standard for justice in the workplace," per ABC News. Uber's chief HR officer, general counsel, and board member Arianna Huffington will also assist in the investigation into Susan Fowler's claims. Kalanick says he's debunked at least one claim, though: Fowler said only 6% of Uber's engineers were women as of December, but Kalanick claims women make up 15% of those employed in engineering, product management, and science roles at Uber. That figure "has not changed substantively in the last year," he adds, per the Guardian. While the CEO didn't offer any figures on women in management roles at Uber, he did promise a "broader diversity report" would be released soon.
