On Jan. 13, five days after the company suspended Trump in light of the deadly riots at the U.S. Capitol, Paxton announced he was launching an investigation into the content moderation policies at Google, Facebook, Twitter, Amazon and Apple.

First Amendment rights and transparency must be maintained for a free online community to operate and thrive, he said in a statement at the time. However, the seemingly coordinated de-platforming of the President of the United States and several leading voices not only chills free speech, it wholly silences those whose speech and political beliefs do not align with leaders of Big Tech companies.

In its filing, however, Twitter maintained that First Amendment protections guaranteed the companys ability to decide what was permissible on its platform, as well as what to remove or restrict. Cooperating with the states request for volumes of highly confidential documents related to content moderation, the company said, would undermine the effectiveness of Twitters policies and compromise its abilities to carry out such moderation.

The company said it tried to work out an agreement with the Texas attorney general to limit the scope of his offices request, which sought all of the companys policies, but the two parties were not able to do so.

Instead, AG Paxton made clear that he will use the full weight of his office, including his expansive investigatory powers, to retaliate against Twitter for having made editorial decisions with which he disagrees, the company said.

Representatives for Twitter and the Texas attorney general did not immediately respond to requests for comment.

Paxton has sparred with the social media platform in the past over its content moderation policies, asserting in a Fox News opinion piece last May that Twitters fact checkers were politically biased against Trump.
