After a nationwide suspension of billionaire Elon Musk’s X platform in Brazil, social media users — including former independent presidential candidate Robert F. Kennedy Jr. — are misrepresenting a years-old video of Vice President Kamala Harris to falsely claim that the Democratic presidential nominee has threatened to censor both X and Musk. But the clip is from 2019 and shows Harris speaking about whether then-President Donald Trump’s profile should be removed from the platform, formerly known as Twitter, and how there needs to be increased accountability for social media companies.
