He is the son of drug lord Joaquin "El Chapo" Guzmán, who was sentenced to life in prison plus 30 years in the US.
Guzmán, 62, had been found guilty in New York of 10 charges, including drug trafficking and money laundering.
He escaped a Mexican jail through a tunnel in 2015, but was later arrested. He was extradited to the United States in 2017.
