Brazil's former president Jair Bolsonaro on Wednesday denied authorizing the use of his image and voice for a deepfake video in which he endorses his son Flavio Bolsonaro's candidacy in October elections. The deepfake video was screened as Flavio Bolsonaro officially launched his candidacy on Saturday. Jair Bolsonaro, 71, served several months in prison before being allowed in March to be confined under house arrest due to health issues. On July 13, the Supreme Court barred Flavio Bolsonaro from visiting his father until after the first round of the election, after he read out a handwritten letter from Jair Bolsonaro on social media. Flavio Bolsonaro is the main rival to leftist President Luiz Inacio Lula da Silva, who is seeking a fourth non-consecutive term in office.
