Brazilian President Jair Bolsonaro has challenged the election he lost last month to leftist rival Luiz Inacio Lula da Silva, arguing votes from some machines should be "invalidated" in a complaint that election authorities met with initial skepticism.
Bolsonaro's claim seems unlikely to get far, as Lula's victory has been ratified by the Superior Electoral Court (TSE) and acknowledged by Brazil's leading politicians and international allies. Still, it could fuel a small but committed protest movement that has so far refused to accept the result.
