Trevor Edwards, Nike brand president who was seen as a potential successor to CEO Mark Parker, is stepping down immediately and retiring from the company in August, The Wall Street Journal reports. In an internal memo to staff announcing the departure, Parker disclosed that the company has recently received reports of “behavior occurring within our organization that do not reflect our core values of inclusivity, respect and empowerment.” Parker wrote, “We’ve heard from strong and courageous employees,” but did not specify the nature of the complaints or whether they involved Edwards or other executives; a spokesperson says there are no allegations against Edwards.
