Brasilia's governor Jose Roberto Arruda waves during the inauguration of the Olympic Village in Brasilia in this October 16, 2009 file photo. A kickback scandal involving an opposition governor has highlighted Brazil's persistent political corruption and could hurt the opposition's chances of beating President Luiz Inacio Lula da Silva's candidate in next year's election. The scandal erupted on November 27, 2009 when video footage surfaced showing the governor of the federal district of the capital Brasilia, Arruda, apparently receiving large amounts of cash during his election campaign in 2006.
