Venezuela has released two jailed U.S. citizens following a rare visit to Caracas by a delegation from Washington, D.C. One of the freed prisoners is Gustavo Cardenas, a Citgo oil executive who was arrested in 2017 and convicted of corruption — a charge rejected by the U.S. The other is Cuban American Jorge Alberto Fernández, reportedly accused of terrorism for flying a drone. The White House said talks about releasing American prisoners were not related to a possible easing of sanctions on Venezuela amid the Russian oil ban.
