Sen. Josh Hawley (R-MO) proposed legislation Wednesday to end big tech companies’ legislative immunity, which would prevent them from censoring conservative and alternative viewpoints without significant recourse.

Sen. Hawley proposed the Ending Support for Internet Censorship Act, which updates the way the federal government treats social media companies under Section 230 of the Communications Decency Act (CDA).

The Missouri conservatives’ legislation removes the big tech’s immunity received under Section 230 unless they submit to an external audit that would prove that their algorithms and content-removal policies remain politically neutral. Sen. Hawley’s legislation would only apply to large tech companies such as Google, Facebook, and Twitter, not small and medium-sized tech companies.

“With Section 230, tech companies get a sweetheart deal that no other industry enjoys: complete exemption from traditional publisher liability in exchange for providing a forum free of political censorship,” said Sen. Hawley in a statement Wednesday. “Unfortunately, and unsurprisingly, big tech has failed to hold up its end of the bargain.”

Hawley’s legislation arises as the Donald Trump Department of Justice (DOJ) and the Federal Trade Commission (FTC) will reportedly begin antitrust investigations into America’s largest technology companies.

Other conservatives, such as Rep. Matt Gaetz (R-FL) and Sen. Ted Cruz (R-TX), have proposed eliminating or amending Section 230 to curb big tech companies’ ability to censor conservative and alternative viewpoints.

Sen. Hawley’s legislation would:

The senator continued, “There’s a growing list of evidence that shows big tech companies making editorial decisions to censor viewpoints they disagree with. Even worse, the entire process is shrouded in secrecy because these companies refuse to make their protocols public.”

“This legislation simply states that if the tech giants want to keep their government-granted immunity, they must bring transparency and accountability to their editorial processes and prove that they don’t discriminate,” Hawley added.
