Facebook is really, seriously working on its fake news problem, Sheryl Sandberg says

Facebook can't escape criticism about its role in distributing "fake news." Confronted with what you might call a gentle probing on The Today Show on Thursday, a top exec said the company is "working on it." 

"We've been working on this for a long time, and we've taken important steps, but there's a lot more to do," Sheryl Sandberg, Facebook's chief operating officer, told Today anchor Savannah Guthrie. "We're working on it, because misinformation is something we take seriously and something we're going to continue iterating on the surface."
