Republican lawmakers have expressed concern that Big Tech companies like Twitter, Facebook and Google are using their online platforms to blacklist or censor conservative viewpoints. Twitter flagged the accounts of President Donald Trump and his campaign multiple times for election-related posts the social media giant said violated its content rules. Twitter also froze the New York Post’s account for more than two weeks after the publication reported on Hunter Biden’s alleged laptop. Facebook took down multiple advertisements by the Susan B. Anthony List, a pro-life organization, and has censored similar content from other pro-life groups. Facebook chief executive Mark Zuckerberg admitted in 2019 there “clearly was bias” over the monitoring of pro-life content on the platform, Fox News reported.
