BRASILIA (Reuters) - President Dilma Rousseff said on Tuesday she will not resign in Brazil's worst political crisis in two decades, calling an opposition move to impeach her a "coup d'etat" against democratic rule because she had committed no crime.
A corruption scandal that has reached her inner circle threatened to implicate more people after the country's largest engineering firm Odebrecht decided to cooperate with prosecutors investigating a huge political bribery scheme.
