Former Venezuelan President Nicolas Maduro returns to a New York courtroom Thursday as he seeks to have his drug trafficking indictment thrown out over a geopolitical dispute over legal fees.

Axar.az informs, citing AP, Maduro’s lawyer contends that the U.S. is violating the deposed leader’s constitutional rights by blocking Venezuelan government funds from being used to pay his legal costs.

Nicolas Maduro and his wife Cilia Flores have been held in a Brooklyn jail for nearly three months after being captured from their presidential compound in Caracas during an overnight U.S. military operation in early January.

Both remain jailed at a detention center in Brooklyn, and neither has asked to be released on bail. Judge Alvin Hellerstein has yet to set a trial date, though that could happen at the hearing.
