Multiple social networking companies suspended accounts of Donald Trump after he posted in support of the US Capitol attackers.
In a social media message to protesters Mr Trump 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”.
Twitter restricted the president for 12 hours but added that the president’s account could remain locked for good if the tweets were not removed.
While Facebook and Instagram banned Mr Trump from posting for 24 hours.
YouTube also removed the video.
Snapchat also stopped Mr Trump from creating new posts, but did not say if or when it would end the ban.
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”.
