“I’m really sorry that this happened,” the Facebook () CEO told CNN’s Laurie Segall in an exclusive TV interview on Wednesday.
The revelation put Facebook and Zuckerberg under the microscope for their handling of user data and privacy.
Zuckerberg addressed the scandal publicly through a Facebook post on Wednesday. He wrote that the company made “mistakes” and outlined how it has changed its policies to make sure that user data is protected.
“I wish we’d taken those steps earlier,” Zuckerberg told Segall. “That … is probably the biggest mistake that we made here.”
