The move is a stunning fall from grace for Trump, who assembled a massive national following, in large part through prolific use of his Twitter feed. The platform was his preferred tool for announcing major changes in federal policy — and even changes in personnel. He occasionally fired Cabinet secretaries and aides via tweet.
He took pride in his ability to get around the mainstream media and drive cable news with tweets he compared to "a rocketship."
"I call Twitter a typewriter," Trump told a White House summit with right-wing social media provocateurs in 2019.
"I go, 'Watch this.' Boom. I press it, and within two seconds, 'We have breaking news,'" he said.
But Trump used his Twitter account to do more: routinely disparage, attack and threaten his rivals. Researchers say Trump's tweets supercharged falsehoods about racial justice protesters, the coronavirus and the election, among many other topics.
Inspired and encouraged by the president's rhetoric — on and off social media — thousands of rioters attacked the U.S. Capitol building on Wednesday. That marked a turning point for Twitter, but it initially stopped short of permanently banning the president and instead suspended his account for 12 hours.
At the White House, officials did not immediately respond to requests for comment. Jason Miller, who was a top adviser to Trump during his campaign, called the ban "disgusting" and said "Big Tech" wanted to "cancel" the 75 million people who voted for Trump.
