Brazil’s first lady, Janja Lula da Silva, expressed her frustration towards billionaire Elon Musk during a G20 social event on Saturday, where she emphasized the importance of regulating social media to combat misinformation.

As she was speaking, a ship’s horn blared, prompting her to quip, “I think it’s Elon Musk,” before asserting, “I’m not afraid of you, screw you, Elon Musk.” Musk, who owns the social network X, responded to a video of her comments with a laughing emoji. He further commented, “They are going to lose the next election,” referring to President Luiz Inacio Lula da Silva.

Janja Lula da Silva addressed attendees at an event leading up to the G20 summit in Rio de Janeiro, scheduled for Monday and Tuesday.

Earlier this year, Musk’s social media platform faced a month-long suspension in Brazil due to its failure to appoint a legal representative in the country and its disregard for court orders to block accounts accused of disseminating “fake news” and hate speech.
