Social media giants Facebook and Twitter showed their Democratic biases Wednesday when the banned a damning story of Hunter Biden’s emails detailing how he was selling access to his father then-Veep Joe Biden.

The exclusive story broken by The New York Post was banned by both Facebook and Twitter from being shared on the social media platforms. Facebook, led by CEO Mark Zuckerberg, said it was looking to it’s outside “fact checkers” to verify the story before it would allow users to share the link. Twitter’s CEO Jack Dorsey sent the following tweet late Wednesday:

Not only did Twitter block the story from being shared, but they also blocked many accounts including the Post’s main feed and White House Press Secretary Kayleigh McEnany’s account for much of the day alleging the story violated “our rules against distribution of hacked material.”

These actions prompted many Republican Senators including Josh Hawley to demand answers from the Silicon Valley tech giants.

“@Twitter @jack this is not nearly good enough. In fact, it’s a joke. It’s downright insulting. I will ask you – and @Facebook– to give an explanation UNDER OATH to the Senate subcommittee I chair. These are potential violations of election law, and that’s a crime,” the Senator wrote in a tweet.

The controversy only heightens the drama behind the question of whether these social media firms should be afforded the protections under Section 230 of the Communications Decency Act. The provision says online platforms are not legally responsible for what users post.

That means they do not consider themselves publishers. However when these social media giants outright ban stories or users they are in fact publishers. Therefore they should lose that provisional treatment.
