Stevie Wonder has called for "narcissistic and dangerous" President Donald Trump to be removed from office following riots in Washington DC.
The 'Superstition' hitmaker observed the scenes of violence at the Capitol "in disbelief" and urged politicians to invoke the 25th amendment - which legislates for the Vice President to take control if the Commander-in-Chief is "unable to discharge the powers and duties of his office" - and end the former 'Apprentice' star's term two weeks earlier than planned.
He tweeted: "It is time for the leaders of this country to invoke the 25th Amendment. Isn’t it obvious? Today has made me sad with disbelief with what is happening in my country, a country that has inspired my songs of hope and love.
"I am heartbroken and astounded that this narcissistic and dangerous president would put lives in danger and encourage violent sedition against our government. That man is no longer able to serve as President because he can't accept defeat. Can we afford 2 more weeks? I say NO!(sic)"
Cardi B highlighted the "irony" between the violent protests and the was peaceful Black Lives Matters protests were handled over the summer.
She tweeted: "The irony is pretty funny.........weren’t people just wild animals in the summer for demanding justice and now? [thinking face emojis]......Let me just watch.(sic)"
Ashton Kutcher insisted there was nothing "patriotic" about the protesters' conduct.
He wrote: "Support the peaceful transition of power!!!!!!!! That’s being a patriot!(sic)"
Mark Ruffalo insisted the actions had "been allowed", despite widespread outrage.
He posted: "Imagine if this was our side. There would be rivers of our blood in the streets and not a single one of us would be armed. This has been allowed. #CoupAttempt (sic)"
Director Ava DuVernay highlighted images of the protesters inside the Captol buildings and contrasted them with Trump's much-condemned speech in which he asked the group to leave as she branded them "terrorists".
She shared an extract which read: "“I know your pain. I know your hurt. But you have to go home now... We love you. You’re very special.”
- Trump to his terrorists (sic)"
Selena Gomez condemned social media platforms and their executives for facilitating the behaviour which led to the riots.
She tweeted: "Today is the result of allowing people with hate in their hearts to use platforms that should be used to bring together and allow people to build community.
"Facebook, Instagram, Twitter, Google, Mark Zukerberg, Sheryl Sandberg, Jack Dorsey, Sundar Pichai, Susan Wojcicki - you have all failed the American people today, and I hope you're going to fix things moving forward."
Shortly after Trump posted his video message to the group - in which he continued to make allegations of election fraud and insisted the vote had been stolen from him - Twitter locked his account for 12 hours and warned any further violations would "result in permanent suspension.
The platform wrote: "As a result of the unprecedented and ongoing violent situation in Washington, D.C., we have required the removal of three @realDonaldTrump Tweets that were posted earlier today for repeated and severe violations of our Civic Integrity policy.
"This means that the account of @realDonaldTrump will be locked for 12 hours following the removal of these Tweets. If the Tweets are not removed, the account will remain locked."
Facebook and YouTube also removed Trump's video to diminish "the risk of ongoing violence", while both Facebook and Instagram have banned him from posting for 24 hours.
