SAN FRANCISCO — Ride-hailing service Uber Technologies Inc. is responding to a former employee’s allegations of sexual harassment by a supervisor with an internal review led by former U.S. Attorney General Eric Holder Jr., top executives, board member Arianna Huffington and the in-house legal department.

Because the claims against the company include the female engineer’s charges that her repeated complaints to Uber’s human resources department were stonewalled, however, plaintiffs employment lawyers said Uber’s in-house legal department could share some of the blame.
