Sao Paulo , Brazil ( CNN ) Demonstrators took to the streets across Brazil on Sunday , protesting corruption and demanding the impeachment of President Dilma Rousseff . Her administration is struggling amid a weak economy and a massive corruption scandal involving the country 's state-run oil company . `` I love Brazil . I love my country . And I am tired of corruption . We are tired of corruption . It does n't matter which political party you are from , we are tired of being robbed , '' a protester told CNN in Sao Paulo , where people packed the main Paulista Avenue . In Rio de Janeiro , they gathered along Copacabana beach , while in the capital , Brasilia , protesters marched on government headquarters . The mood was festive . Many demonstrators wore the country 's colors -- green , blue and yellow -- waved flags , and chanted : `` Out Dilma . '' Amid complaints about the economy , protesters say they are incensed because Brazilian investigators are unraveling a huge money-laundering and bribery case centered around Petrobras , the country 's national oil company . Dozens of politicians , some in Rousseff 's party , are accused of accepting millions in payments . The President has not been implicated in the investigation , but she was the Energy Minister and chairwoman of Petrobras during much of the time that the alleged corruption took place . Why are protesters furious with Brazil 's President ? Sunday night Rousseff sent two of her ministers to address the nation at a televised press conference . The justice minister and the general secretary said that the government was listening and would announce changes in several days designed to combat corruption . The announcement did little to quiet the protests in some cities . Many protesters banged pots and pans and honked car horns . CNN iReporter Bruno Teles with Avant Drones shot aerial footage of the crowds in Sao Paulo . He said , `` Brazilians are tired of such corruption , lies and [ the ] bad economy . '' Before becoming the country 's first female president in 2011 , Rousseff , from the Workers ' Party , was chief of staff to former President Lula da Silva . She won re-election in October , in one of the tightest races in recent years , but has since seen her approval rate plummet along with the economy . Brazil is headed into recession again this year , inflation is up and the currency is at a 12-year low . Rousseff 's approval rating down to 23 % from 42 % at the end of 2014 , according to DataFolha . The economy is expected to contract this year and the real has plummeted 23 % against the dollar .
