Bribes from Brazilian construction giant Odebrecht financed the presidential campaign that brought Mexico's Enrique Pena Nieto to power in 2012, the ex-boss of state oil firm PEMEX said Tuesday, quoted by prosecutors. Emilio Lozoya, who is on trial, said that a series of bribes exceeding 100 million pesos (about $4.4 million) "were mainly used for the 2012 presidential campaign," Attorney General Alejandro Gertz told reporters. jg/axm/dr/dw
