Trump threatens social media shutdown over Twitter fact-check label

US President Donald Trump on Wednesday threatened to regulate or shut down social media companies for stifling conservative voices, a day after Twitter attached a warning to some of his tweets prompting readers to fact check the president’s claims.

Without offering evidence, Trump again accused such platforms of bias, tweeting: “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.”

The president, a heavy user of Twitter with more than 80 million followers, added: “Clean up your act, NOW!!!!”

Trump’s threat to shut down platforms like Twitter and Facebook was his strongest yet within a broader conservative backlash against Big Tech. Shares of both companies fell.
