An adviser for US President Donald Trump is set to meet with officials from the government of Venezuela’s Nicolas Maduro in Caracas, part of an early effort at engaging with the sanctioned leader of the oil-rich nation.

Six Americans who had been detained in Venezuela in recent months were freed by the government of President Nicolás Maduro.

US President Donald Trump sent an envoy Friday to Venezuela to warn leftist leader Nicolas Maduro to accept the unconditional return of deported Venezuelans or face consequences.
