Donald Trump's use of social media attracted attention worldwide since he joined Twitter in May 2009. Over nearly twelve years, Trump tweeted around 57,000 times, including about 8,000 times during the 2016 election campaign and over 25,000 times during his presidency. The White House said the tweets should be considered official statements. When Twitter banned Trump from the platform in January 2021 during the final days of his term, his handle @realDonaldTrump had over 88.9 million followers. For most of Trump's first presidency, his account on Twitter, where he often posted controversial and false statements, remained unmoderated in the name of "public interest". Congress performed its own form of moderation, and in the face of this political censure, his tweets only accelerated.
During his 2020 reelection campaign, he falsely suggested that postal voting or electoral fraud may compromise the election, and after his election loss, Trump persistently undermined the election results, and his tweets played a role in inciting the attack of the US Capitol. Though the Senate eventually acquitted Trump during his second impeachment, social media companies swiftly banned him. Facebook and Instagram banned him for two years. During the first week in January 2021 that Trump was banned on several platforms, election-related misinformation declined 73 percent, according to research analytics firm Zignal Labs. In November 2022, Twitter's new owner, Elon Musk, reinstated his account, although Trump had stated he would not use it in favor of his own social media platform, Truth Social. In April 2023, at his arraignment hearing, Trump was warned by Acting New York Supreme Court Justice Juan Merchan not to use social media to incite violence.
