President Donald Trump on Monday signed an executive order banning "federal censorship" of online speech. "Over the last four years, the previous administration trampled free speech rights by censoring Americans' speech on online platforms, often by exerting substantial coercive pressure on third parties, such as social media companies, to moderate, deplatform or otherwise suppress speech that the federal government did not approve," the executive order read. The order bans federal officials from any conduct that would "unconstitutionally abridge the free speech of any American citizen." It also prohibits taxpayer resources from being used to curtail free speech and instructs the Department of Justice and other agencies to investigate the actions the Biden administration took and to propose "remedial actions." Limiting communication and coordination between Big Tech companies and the federal government could jeopardize public safety in natural disasters and health emergencies, some observers warned. Multiple lawsuits have accused the Biden administration of leaning on social media platforms to take down lawful speech about the COVID-19 pandemic and the 2020 election. Meta CEO Mark Zuckerberg recently backed up those claims, alleging senior administration officials pressured his employees to inappropriately take down or throttle content during the pandemic. The Biden administration has said it was combating the spread of falsehoods to protect the public.
