Brazil's former President Luiz Inacio Lula da Silva greets supporters who have gathered outside his residence, in Sao Bernardo do Campo, in the greater Sao Paulo area, Brazil, Saturday, March 5, 2016. Brazilian police hauled in the former president for questioning Friday, in a sprawling corruption case centered on the Petrobras oil company that has already ensnared some of the country's top lawmakers and richest and most powerful businessmen. Silva reacted with indignation, saying the Petrobras corruption case has become a political witch hunt targeting him and his governing Workers' Party. (AP Photo/Andre Penner), APTOPIX
