Brazil's President Luiz Inácio Lula da Silva, a vocal critic of U.S. President Donald Trump, won reelection Sunday, securing a fourth non-consecutive term and keeping Latin America's largest economy independent from Washington. With 100% of votes counted, Brazil's electoral court declared Lula's lead unassailable over opponent Flávio Bolsonaro, son of jailed former President Jair Bolsonaro. The result followed a Supreme Court decision to extend voting by two hours, which Bolsonaro may legally challenge. Lula's victory bucks a regional trend of Trump-aligned right-wing leaders and leaves Mexico and Brazil with left-of-center presidents. The 80-year-old, who begins his term Jan. 5, 2027, joins Trump and Nicaragua's Daniel Ortega as the Americas' oldest presidents.
