LIMA Ė Former first lady Nadine Heredia invoked her right to keep silent on Wednesday before a Peruvian congressional committee that is investigating her for alleged usurpation of official functions during the 2011-2016 administration of husband Ollanta Humala.
Heredia said lawmakers should forward their questions to the Attorney Generalís Office, which is conducting its own probe of her conduct as first lady, Oversight Committee chairman Hector Becerril said following the closed-door hearing.
The AG Office is also examining allegations that Heredia engaged in money laundering to finance the Peruvian Nationalist Party, founded by her and Humala.
Heredia, 40, told reporters after the session with the committee that she declined to answer the membersí questions because of a lack of due-process guarantees.
The former first lady had requested earlier that Becerril be recused from the matter because of his derogatory public comments about her.
Heredia said she has already provided prosecutors with responses to most of the questions posed on Wednesday by lawmakers, adding that she will continue to cooperate fully with the AG Officeís investigation.
She said that she will remain on leave from her new position as director of the UN Food and Agriculture Organization office in Geneva as long as necessary to resolve her legal situation.
Heredia traveled to Switzerland to take up the post after her appointment was announced late last month, but she heeded a subsequent court order to return to Peru.
The 54-year-old Humala, who was elected in 2011, completed his five-year presidential term on July 28.
