The chief executive officers of Twitter and Facebook took the stand on Tuesday to testify, again, about allegations of anti-conservative bias on their platforms. Mark Zuckerberg and Jack Dorsey were subpoenaed in October to appear at Tuesday’s hearing with the Senate judiciary committee in order to “review the companies’ handling of the 2020 election”. Republican lawmakers frequently allege – without evidence – censorship of conservative views, but this particular hearing was called in response to the companies’ handling of a New York Post article about Joe Biden. When the story was published in October, Twitter took unprecedented steps to limit its circulation, blocking users from posting links or photos of the report. At the time, Twitter said the measures were taken due to “the origins of the materials” included in the article, which were allegedly pulled from a computer that had been left by Hunter Biden at a Delaware computer repair shop in April 2019. Twitter policies prohibit “directly distribut[ing] content obtained through hacking that contains private information”. The company later walked back on its response, tweeting that the communication around the actions on the article “was not great”. It also changed its hacked materials policies in response to the outcry. Facebook took a less aggressive stance, placing some limitations on the article due to questions about its validity. In his opening statement, Dorsey explained again the company took action against the New York Post tweet due to “the origins of the materials” included in the article and said that Twitter upon further review decided that action was wrong. “I hope this illustrates the rationale behind our actions and demonstrates our ability to take feedback,” Dorsey said. “Mistakes and changes were all transparent to the public.”
