Uber Technologies Inc. Chief Executive Officer Dara Khosrowshahi testified that he fired the company’s chief security officer soon after taking the helm in 2017  “because I couldn’t trust his judgment anymore.”

Khosrowshahi was called by prosecutors Friday as a witness against Joe Sullivan, who’s charged with concealing a 2016 hack into company servers that compromised the personal data of 50 million customers and 7 million drivers.
