Brazil is facing its worst political crisis in over two decades as opponents of Brazilian President Dilma Rousseff attempt to impeach her on corruption charges. But Rousseff is refusing calls to resign, saying the impeachment proceedings against her amount to undemocratic attempts by the right-wing opposition to oust her from power. On Wednesday, former Brazilian President Luiz Inácio Lula da Silva called the impeachment proceedings against Rousseff an attempted "coup d’état." We speak to Pulitzer Prize-winning journalist Glenn Greenwald. His piece, "Brazil Is Engulfed by Ruling Class Corruption—and a Dangerous Subversion of Democracy," recently was published by The Intercept.
