Brazil's former President Luiz Inacio Lula da Silva greets supporters in front of the metal workers union headquarters in Sao Bernardo do Campo, Brazil, Saturday, April 7, 2018. Da Silva, the once wildly popular leader, who rose from poverty to lead Latin America's largest nation, had until 5 p.m. local time Friday, to present himself to police in the city of Curitiba to begin serving a sentence of 12 years and one month for a corruption conviction but he defied the order to turn himself in.
