On 7 January 2021, Twitter temporarily locked the account of US President Donald Trump after multiple controversies, including his use of the platform to undermine the results of the 2020 presidential election and incite the 2021 United States Capitol attack. On 8 January, Twitter permanently suspended Trump's account, citing his violation of Twitter's Glorification of Violence guidelines. Twitter also suspended or heavily moderated accounts that enabled Trump to circumvent his ban, including the official @POTUS handle. Trump congratulated Nigeria for blocking Twitter, and wrote that he had hosted Zuckerberg for dinner in White House. Twitter was criticized for banning Trump but deleting Ali Khamenei tweets. Twitter also suspended @DJTDesk.
