Facebook CEO Mark Zuckerberg finally broke his silence today (March 21) following the revelation that Cambridge Analytica, a consultant for the 2016 Trump presidential campaign, harvested the data of 50 million Facebook users without permission.

“We have a responsibility to protect your data, and if we can’t then we don’t deserve to serve you,” Zuckerberg said in a statement posted to his Facebook page.
