What does Maduro's son say about the condition of his father and his wife in prison?

The former Venezuelan president Nicolás Maduro, aged 63, exercises daily in the New York prison, his son, Nicolas Maduro Guerra, stated during a march in Caracas.

Maduro and his first lady Cilia Flores, aged 69, were captured on January 3 by American special forces following a military operation. They will appear on Thursday before a federal court, being accused of facilitating international drug trafficking. 'We are mobilizing for their release,' said 'Nicolasito', emphasizing that his father is 'strong' and 'full of energy'. Thursday's hearing will address procedural issues before examining the merits. Maduro is in an isolated cell at the Metropolitan Detention Center in Brooklyn, without access to the internet or newspapers.
