Alex Cifuentes (second left), a close associate of the accused Mexican drug lord Joaquin "El Chapo" Guzman, (front right) is seen testifying in this courtroom sketch in Brooklyn federal court in New York, US, January 15, 2019. Reporters shared that Nieto is accused of initially asking for $250 million, but settling on $100 million.
Lichtman asked Cifuentes about statements he made to American officials in November 2017 claiming the president told Guzman he "didn't need to stay in hiding" if he paid the money.
He tweeted: "The declarations of the Colombian drug trafficker in NY are false, defamatory and absurd" and said Mr Pena Nieto's government had "located, detained and extradited" El Chapo.
Alex Cifuentes spoke about the alleged bribe to former President Enrique Pena Nieto while being cross-examined at Guzman's murder and drug conspiracy trial in NY. The allegation came as the Colombian drug lord Alex Cifuentes Villa took the witness stand in a federal district court in Brooklyn.
Cifuentes was a key figure in the Sinaloa Cartel, of which Guzman was the head, and claimed that he had heard Guzman bragging about the bribe to the former president. Peña Nieto has not responded to the claim but has previously denied charges of corruption. Nieto left office a year ago.More news: Canadian's death sentence in China 'horrific', family says
Nieto is the former President of Mexico, who held office from 2012 to 2018.
But the president ended his term a much diminished figure, pummeled by conflict-of-interest scandals, rampant crime and a lackluster economy.
Guzman added that it under Pena Nieto's administration that Guzman was found, detained and extradited. He previously served as governor of the State of Mexico.
The 61-year-old drug lord made headlines twice for breaking out of prison, including escaping through a mile-long tunnel in 2015. Guzman allegedly founded the Sinaloa Cartel, an global money laundering, drug trafficking and organized crime network that was established during the mid-1980s, and widely considered one of the world's most powerful illicit drug organizations. However, during the course of Tuesday's testimony, he also clarified that he was "confused" about the exact amount of bribe paid to Nieto.
