Legal Twitter lit up overnight as lawyers largely denounced an executive order President Donald Trump is expected to sign Thursday limiting free speech protections for social media platforms.

The president is expected to ask for a review of protections provided by Section 230 of the Communications Decency Act, which largely protects providers from liability for content posted on their platforms, according to various media reports. The current form circulating on social media calls to strip that immunity if online publishers restrict access to content in a way that is “deceptive or pretextual” or “inconsistent with an online platform’s terms of service.”
