A close friend of Lula, Pinguelli was appointed as president of Eletrobrás, and found himself at odds with Rousseff on several occasions, considering an early resignation once. He was ironic about Rousseff's alleged mood swings, being quoted as saying that "this lady formats her disk every week." Pinguelli eventually left the federal government in 2004. Mauricio Tolmasquim, a member of the transition government which shared a vision of the energy sector similar to Rousseff's, was invited by her to be the executive secretary of the ministry. He stated that once they got to know each other better, Rousseff started shouting with him occasionally. "It's her way. It's not personal. And in five minutes everything is okay," he said. Sauer, who took over the gas and energy department of Petrobras, also clashed with the minister, who repulsed his ideas of a statist model. Sometimes the clashes between them were so serious that Lula's intervention was necessary. Sauer left the state oil company in 2007. Another one which had disagreements with the minister on energy issues was the former Congressman Luciano Zica. For him, "Dilma is the most democratic person in the world, as long as you agree 100% with her." He recently left PT and joined the Green Party along with Marina Silva.
