In January 2014, lawyer Rudi Alfonso alleged several legislators had threatened to have Karen fired if Pertamina did not give them money. “She has often received threats that she will be fired. But she never responded to such requests," he said. Rudi Rubiandini, the former head of Indonesia's upstream oil-and-gas regulator SKKMigas, had claimed Karen provided gratuities to members of the
House of Representatives Commission VII on energy. In April 2018, it was reported the Attorney General's Office had named Karen a corruption suspect in relation to Pertamina's investment in the Basker Manta Gummy (BMG) block in
Australia in 2009. The alleged corruption was said to have caused state losses of Rp 568 billion (about US$40 million). She was sentenced to eight years of prison in June 2019. Karen immediately filed to appeal the verdict. The
Supreme Court in 2020 accepted the appeal and overturned her conviction. She was detained again in september 2023 allegedly being involved for ongoing graft investigation related to the company's procurement of liquefied natural gas (LNG) over the past decade. ==Personal life==
