Venezuela's Bid for Deal with Biden at Colombia Summit.

Venezuela seeks a deal with the United States on a prisoner exchange and sanctions relief at discussions on the sidelines of a multinational conference in Colombia on Venezuela's political crisis. Talks in Colombia could prove a new chance for the freedom of U.S. nationals detained in Venezuela. The summit is set to bring together officials from around 20 nations and is expected to mark the latest opportunity to advance deadlocked negotiations between Maduro and a divided opposition.
