In the testimony, Walker largely summarizes the election security efforts put into place by the company over the past months. He notes Google's work to confront activity from Russia's Internet Research Agency as well as a recent misinformation campaign based out of Iran. He also discusses four major steps taken to secure election advertising including its verification program, in-ad disclosures, its political advertising transparency report and its searchable election ad library. Additionally, Google's testimony describes the efforts made to protect election campaigns, political candidates and news sites from cyberattacks, which include the company's Advanced Protection program and Project Shield.
"Combating disinformation campaigns requires efforts from across the industry," wrote Walker. "We'll continue to work with other companies to better protect the collective digital ecosystem, and, even as we take our own steps, we are open to working with governments on legislation that promotes electoral transparency." Walker said he would be in Washington, DC to brief members of Congress on the company's work.
