RIO DE JANEIRO—When Brazilian President Dilma Rousseff was kicked out of power, she became the biggest casualty of a massive corruption probe that is roiling Latin America’s largest country—even though she was never personally implicated in the scheme.
With Rousseff’s permanent departure from the presidency on Wednesday, the big question is: What happens now to the investigation at the state oil company Petrobras?
