Two weeks after The New York Times revealed Facebook’s controversial work with Republican opposition research firm Definers Public Affairs, Facebook COO Sheryl Sandberg has changed her story in significant ways.

The latest revelation: Sandberg herself directed Facebook’s communications team to probe the financial ties of George Soros, left-leaning billionaire and frequent political target of the right. The new reporting cites an email between Sandberg and a Facebook senior executive that was circulated more broadly to senior comms and policy staff. “Sheryl sent an email asking if Mr. Soros had shorted Facebook’s stock,” a Facebook spokesperson said in a statement provided to TechCrunch.

As TechCrunch has learned — and Sandberg herself alluded to in a statement — Sandberg was also looped into emails about Definers, the team that later conducted research into Soros on Facebook’s behalf. Definers was also integrated more deeply into Facebook’s communications operations than has previously been reported.

People knowledgeable of Facebook’s inner workings and those outside of the company expressed surprise at Sandberg’s choice to initially deny any knowledge of the relationship with Definers. “Mark issued an absolute denial and Sheryl followed, which surprised all of us because we knew her denial wasn’t true,” a source familiar with the firm’s work with Facebook told TechCrunch. “She’s pretty exposed right now.”

When the Definers story broke, Mark Zuckerberg issued a swift statement denying any knowledge of the firm’s work. Sheryl Sandberg also denied any knowledge of Definers, though walked that statement back four days later when Facebook’s recently departed policy and communications head Elliot Schrage took the blame for the work.

In a statement coupled with his, Sandberg said that she initially did not remember a firm named Definers but upon review admitted that the firm’s work with Facebook was “incorporated into materials” presented to her and that the firm was referenced in “a small number of emails” she had received. Facebook’s decision to hire Definers, a corporate-facing outgrowth of the Republican America Rising PAC known for its fierce opposition research, proved to be a deeply controversial departure from Silicon Valley ethical norms.

How the Definers relationship began

As TechCrunch has learned, Definers began its work with Facebook through Facebook’s content communications team and Facebook’s director of Policy Communications, Andrea Saul, who previously worked under Definers founder Matt Rhoades on Mitt Romney’s 2012 presidential campaign. Saul served as the national press secretary for the campaign from early 2011 to November 2012 under Rhoades, who managed the campaign. After the Romney campaign ended, Saul went to work doing communications for Sheryl Sandberg’s nonprofit LeanIn.org and found her way to Facebook in 2016.

Some members of Facebook’s communications team are former Republican campaign staffers and strategists with ties to the outside firm that Facebook controversially brought in to support its own internal PR efforts. As TechCrunch previously reported, those ties are largely through Romney’s campaign.

After it was set into motion, Facebook’s relationship with Definers was mostly overseen by Andrea Saul, Tom Reynolds and Ruchika Budhraja in Menlo Park. In Washington, D.C., Definers was handled by Andy Stone under Facebook’s chief lobbyist, Joel Kaplan. Kaplan, who worked in the George W. Bush administration with Definers’ founder and its president, was also in the loop, given his high-level policy role and position as a strong in-house Republican voice among many at Facebook. Kaplan made headlines recently when he made a public show of support for Brett Kavanaugh, the Supreme Court nominee who was accused of sexual violence and later confirmed.

As TechCrunch previously reported, many members of Facebook’s communications team are former Republican campaign staffers and strategists with ties to the outside firm that Facebook controversially brought in to support its own internal PR efforts. Facebook’s Tucker Bounds also has close ties to Definers through his friend Tim Miller, who helped create America Rising, the political action committee prong of the firm. His role in the relationship with Facebook, if any, is not clear.

It’s true that Definers came on board initially for more generic PR support — not oppo research per se — and that’s how the firm’s involvement was framed in an email introducing them into Facebook’s own team. According to a source who spoke with TechCrunch, “The work that they were doing initially was nonpartisan, it was media monitoring.” Definers provided Facebook with its own press lists and engaged in other more mundane day to day PR activities.

Over time, Facebook leaned more heavily on the outside firm. Definers worked closely with Facebook’s policy communications team, checking in through weekly calls. While legal firm WilmerHale prepared the Facebook CEO and COO for their time on the stand, Definers also assisted with all three Congressional hearings that brought Facebook before Congress, including Zuckerberg and Sandberg’s hearings. For Sandberg’s hearing, Definers handled the crisis PR responding to the event and the coverage around the testimony.

“Facebook consultants are on very short leashes,” a source familiar with the work told TechCrunch. “Everything that Definers shared with media was approved by a Facebook employee.” While an outside agency might have more autonomy in working with a different company, Facebook was closely involved in the firm’s work and was likely aware of all of its plans and dealings. “Definers knows where the bodies are buried,” the source told TechCrunch.

So far nothing has turned up to indicate that Zuckerberg, like Sandberg, had prior exposure to the firm’s work. Given his general disinterest in media relations, it is believable that Mark Zuckerberg had no awareness of Definers or the communications team’s deep and often out in the open ties with the external Republican communications firm. Zuckerberg is far less involved in the strategic decisions that go into the way Facebook positions itself to the outside world than Sandberg herself.

Facebook’s communications team is an infamously well-oiled machine and that machine is often put to use to protect Sandberg and promote her agenda — at times over Facebook’s own interests. If Sandberg’s latest and perhaps most surprising admission will at last strain trust in her leadership to a breaking point remains to be seen.

Update: Facebook asked for us to include their most recent full statement on Sandberg in this story.

“As Elliot said last week, we researched potential motivations behind George Soros’s criticism of Facebook in January 2018. Mr. Soros is a prominent investor and we looked into his investments and trading activity related to Facebook. That research was already underway when Sheryl sent an email asking if Mr. Soros had shorted Facebook’s stock. Sheryl never directed research on Freedom from Facebook. But as she said before she takes full responsibility for any activity that happened on her watch.”
