 In May 2016, the Chilean Public Ministry began to investigate the irregular financing from Soquimich (SQM) to her party (being one of the edges of Soquimich case) whilst she was president of the PPD through false vouchers issued by Chile Ambiente — foundation linked to the party, controlled by Patricio Rodrigo (PPD's militant too) — between 2011 and 2012 which made possible the receipt of CLP$57 million.On 15 May, in a press release she declared, "I would like to clarify that, as president of the PPD, the financing arrangements that I supported were attached to the law "(...).I did not ask Patricio Rodrigo, neither direct nor indirectly, any matter related to the party's financing."
