Facebook’s outgoing Head of Communications and Policy Elliot Schrage has taken the full responsibility for hiring a Republican-owned political consulting and PR firm Definers Public Affairs that is alleged to have “dug up dirt” on competitors.

“We had not heard such criticism from him before and wanted to determine if he had any financial motivation. Definers researched this using public information,” said Schrage.

Sandberg said it was never anyone’s intention to play into an anti-Semitic narrative against Soros or anyone else. “Being Jewish is a core part of who I am and our company stands firmly against hate. The idea that our work has been interpreted as anti-Semitic is abhorrent to me — and deeply personal,” she wrote late Tuesday.
