Top lawyers from Google, Facebook, and Twitter who testified in front of Congress this week about Russian interference in the 2016 presidential election had Big Law back up.

Attorneys from three law firms — WilmerHale, Mayer Brown and Debevoise — have been prepping them as witnesses, and earlier helped conduct internal reviews to help the GCs understand what actually happened at their own companies during the election.

The assistance came ahead of the most revealing look to date at how each of the three tech companies may have been exploited by Russian operatives. Testimony came from the social media giants’ general counsel — Colin Stretch of Facebook, Richard Salgado and Kent Walker of Google and Sean Edgett of Twitter.

In three separate hearings, the GCs had to answer questions under oath about whether their companies delivered fake information to voters. The heightened scrutiny of the companies and the sensitive nature of the subject meant that the GCs had the dual task of steering their companies through a PR crisis while making sure to stay on the right side of the truth in the process.

“In hindsight, we should have had a broader lens,” said Stretch , when asked how Facebook could have missed the fact that electoral ads on its network, paid for in rubles, were coming from Russia. “There were signals we missed.”

Raj De of Mayer Brown, and the former general counsel of the National Security Agency, advised Google, while David O’Neil, a former Justice Department lawyer with Debevoise & Plimpton, represented Twitter.

Meanwhile, Reginald Brown, the head of WilmerHale’s congressional investigations group, represented Facebook, the company that took perhaps the most heat of the three.

That’s according to two people familiar with the matter, but it’s no secret within Washington’s clubby legal circles: O’Neil sat directly behind his Twitter client at the Congressional hearing and Brown’s fellow WilmerHale partner, Anjan Sahni, was spotted on-scene as well.

Spokespeople at Wilmer, Mayer Brown and Debevoise either didn’t respond to a request for comment or declined comment, but below we’ve listed some details about the lawyers that we gathered via law firm bios and other publically available sources.
