From a BBC report: Russian operatives, likely working from St Petersburg, provoked angry Americans to take to the streets, a US Senate committee heard on Wednesday. The May 2016 protest, arranged by a group named Heart of Texas, was one example of Kremlin-backed efforts to destabilise the American electoral process. Lawyers for three technology companies -- Facebook, Twitter and Google -- were told they were grossly underestimating the scale of the problem. "You just don't get it," said California Senator Dianne Feinstein. "What we're talking about is a cataclysmic change. What we're talking about is the beginning of cyber-warfare." She added: "We are not going to go away, gentlemen. This is a very big deal." [...] Several senators suggested that more hearings and consultation would be needed, expressing their frustration that the companies were not being represented by higher-ranking executives. "I'm disappointed that you're here, and not your CEOs," said independent senator Angus King. From a FastCompany report: Senator Mark Warner (D-VA) had one specific and simple question for Facebook's Colin Stretch. He wanted to know about 30,000 fake accounts Facebook discovered earlier this year that were trying to influence the French election. At the time, Facebook bragged that it was able to discover these accounts and swiftly took them down. Warner wanted to know if Facebook, after discovering these accounts, cross-checked to see if these same accounts also tried to tamper with the U.S. election. "Your leadership bragged about how proactively you were in the French election process," said Warner, "Did you check those accounts [with the U.S. election]?" Stretch couldn't give a straight answer. "The system that ran to take down those accounts -- which were fake accounts of all type and any purpose -- is now active worldwide," he said. Warner wasn't amused. "Just answer my question," he said. "Have you reviewed the accounts you took down in France that were Russian-related to see if they played any role in the American election?" Once again, Facebook couldn't answer.
