Uber operating, marketing chiefs leaving in leadership shake-up

After a tumultuous stock debut, Uber Technologies Chief Executive Officer Dara Khosrowshahi is parting ways with two top lieutenants in a major leadership overhaul. Barney Harford, chief operating officer, and Rebecca Messina, chief marketing officer, are both leaving the company, Uber said.

Uber had largely shielded Harford from public spotlight after he was the subject of an internal review over what some employees described as racially insensitive remarks by the operating chief last year. The investigation was closed last year and found no evidence of discrimination, the company said. Behind the scenes, Harford led much of Uber’s business, though he remained a divisive figure.
