Twitter banned Donald Trump’s account @realDonaldTrump Friday, 8 January 2021.
On January 8, 2021, President Donald J. Trump tweeted:
“The 75,000,000 great American Patriots who voted for me, AMERICA FIRST, and MAKE AMERICA GREAT AGAIN, will have a GIANT VOICE long into the future. They will not be disrespected or treated unfairly in any way, shape or form!!!”

Shortly thereafter, he tweeted again:
“To all of those who have asked, I will not be going to the Inauguration on January 20th.”

Twitter's statement:
"After close review of recent Tweets from the @realDonaldTrump account and the context around them — specifically how they are being received and interpreted on and off Twitter — we have permanently suspended the account due to the risk of further incitement of violence."
