U.S. President Donald Trump will sign an executive order on social media companies on Thursday, White House officials said after Trump threatened to shut down websites he accused of stifling conservative voices.
The officials gave no further details. It was unclear how Trump could follow through on the threat of shutting down privately owned companies including Twitter Inc. The company declined comment.
The dispute erupted after Twitter on Tuesday for the first time tagged Trump’s tweets about unsubstantiated claims of fraud in mail-in voting with a warning prompting readers to fact check the posts.
Separately, a three-judge panel of the U.S. Court of Appeals in Washington on Wednesday upheld the dismissal of a lawsuit by a conservative group and right-wing YouTube personality against Google, Facebook, Twitter and Apple accusing them of conspiring to suppress conservative political views.
In an interview with Fox News Channel on Wednesday, Facebook’s Chief Executive Mark Zuckerberg said censoring a platform would not be the “right reflex” for a government worried about censorship. Fox played a clip of the interview and said it would be aired in full on Thursday.
Facebook left Trump’s post on mail-in ballots on Tuesday untouched.
The American Civil Liberties Union said the First Amendment of the U.S. Constitution limits any action Trump could take. Facebook and Google declined comment. Apple did not respond to a request for comment.
“Republicans feel that Social Media Platforms totally silence conservatives voices. We will strongly regulate, or close them down, before we can ever allow this to happen,” Trump said in a pair of additional posts on Twitter on Wednesday.
The president, a heavy user of Twitter with more than 80 million followers, added: “Clean up your act, NOW!!!!”
Republican Trump has an eye on the November election. “Big Tech is doing everything in their very considerable power to CENSOR in advance of the 2020 Election,” Trump tweeted on Wednesday night. “If that happens, we no longer have our freedom.”
Trump’s threat is his strongest yet within a broader conservative backlash against Big Tech. Shares of both Twitter and Facebook fell on Wednesday.
