The lower chamber of Brazil's Congress on Friday began a debate on whether to impeach President Dilma Rousseff, a question that underscores deep polarization in Latin America's largest country and most powerful economy, according to AP. The crucial vote is slated for Sunday on whether to send the measure to the Senate, where an impeachment trial would take place, prompting the president's suspension from office. Lawmakers backing impeachment allege Rousseff's administration violated fiscal rules. However, many of those pushing for impeachment face grave accusations of corruption themselves. Rousseff's defenders insist she did nothing illegal, and say similar accounting techniques were used by previous presidents.
