Sen. Mark Warner says the “million-dollar question” still unanswered about the Facebook election ads sold to Russian-linked accounts was how the Russians knew whom to target on Facebook.
Warner, the top Democrat on the Senate intelligence panel, told CNN the committee expects this week to begin viewing the 3,000 Russian-linked Facebook ads, which Facebook earlier this month disclosed were connected to more than 450 inauthentic accounts. Facebook agreed last week to turn the ads over to the House and Senate intelligence committees.
Warner’s burning question involves not just the content of the ads but how they were deployed.
