Wednesday, October 12, 2016 Peru ex-president Humala faces graft probePeru’s then-president Ollanta Humala (right) and his wife Nadine Heredia attending a ceremony at the Government Palace in Lima, in 2015. A Peruvian prosecutor said earlier this year that the late Venezuelan president, Hugo Chávez, and two Brazilian construction companies may have bankrolled Humala’s presidential campaigns before he took office in 2011. Representatives for Humala and his wife, Nadine Heredia, did not immediately respond to requests for comment. Earlier this year prosecutors barred Heredia from leaving the country as they probed her finances for evidence of undeclared contributions. But in 2011, after losing the 2006 presidential election, Humala kept Chávez at a distance and won after campaigning in the more moderate style.
