TechCrunch has obtained an internal memo published by Facebook’s outgoing head of public policy Elliot Schrage in which he blames himself for hiring PR firm Definers. He admits to having the company push negative narratives about competitors, but says Facebook did not ask or pay Definers to publish fake news. COO Sheryl Sandberg left a comment on the memo, saying it was never Facebook’s intention to play into anti-semitic theories about George Soros.

The memo includes a Q&A regarding points raised by a New York Times article detailing how Definers worked to spread negative publicity about Google and other tech giants to make Facebook look better, and that the firm’s employees also published biased articles through a news site called NTK Network that’s affiliated with Definers.
