They refused to disseminate the information, authenticate it publicly, and even warned social media companies, knowing that the Trump campaign likely had in its possession a copy of the laptop, that Russian disinformation was about to go main stream.
Mark Zuckerberg, CEO of Facebook, along with Twitter, promptly denied distribution of the story, along with the corporate media calling it Russian disinformation.
