Guatemalan former President Otto Perez Molina is challenging prosecutors' allegations against him in a corruption case, according to AP. Perez Molina says in a court hearing that there's no substance to back up charges of money laundering and illegal enrichment. He accuses a former official who has turned state's witness of being a "compulsive liar." Prosecutors allege that the ex-president received millions of dollars in commissions related to the awarding of public works projects. Perez Molina also faces charges in other corruption cases. He was forced to resign last year. His former Vice President Roxanna Baldetti is accused in the same graft case. She too appeared in court Monday and denied any wrongdoing, calling the allegations "an invention of perverse minds."
