MIAMI (AP) — A businessman who prosecutors say was a major conduit for corruption by Nicolás Maduro’s inner circle has appeared for the first time in Miami federal court after an extradition that has further strained relations between the U.S. and Venezuela’s socialist government. Only hours after Saab was placed on a Department of Justice aircraft on Saturday, Maduro’s government suspended negotiations with Venezuela’s U.S.-backed opposition. It also threw back into jail six American oil executives it accuses of corruption. They had been under house arrest in another politically charged case marked by allegations of wrongful detention.
