Donald Trump has been suspended from Twitter and Facebook after tweeting to supporters who attacked the US Capitol.
In a social media message to protesters, he said "I love you" before telling them to go home. He also repeated false claims about election fraud.
Twitter said it required the removal of three tweets for "severe violations of our Civic Integrity policy".
The company said the president's account would remain locked for good if the tweets were not removed.
It went on to say that "Future violations of the Twitter Rules... will result in permanent suspension of the @realDonaldTrump account".
It means Donald Trump's days on Twitter could be numbered. The president is not known for paying much attention to Twitter's community guidelines.
Meanwhile, Facebook banned Mr Trump for 24 hours. YouTube also removed the video.
Facebook said: "We removed it because on balance we believe it contributes to rather than diminishes the risk of ongoing violence."
His supporters stormed the seat of US government and clashed with police, leading to the death of one woman.
The violence brought to a halt congressional debate over Democrat Joe Biden's election win.
In the House and Senate chambers, Republicans were challenging the certification of November's election results.
Before the violence, President Trump had told supporters on the National Mall in Washington that the election had been stolen.
Hours later, as the violence mounted inside and outside the US Capitol, he appeared on video and repeated the false claim.
He told protesters "I love you" and described the people who stormed the Capitol complex as "patriots".
YouTube said it removed the video because it "violated policies on spreading election fraud".
Twitter initially didn't take down the video, instead removing the ability to retweet, like and comment on it and another tweet.
However, it later removed them, and suspended the outgoing president.
