The U.S. State Department is investigation information that Venezuela violated U.S. sanctions by sending gasoline to Iran.
Arturo Valenzuela, the assistant secretary of state for Western Hemisphere affairs, told a congressional panel "we are looking at that issue" and "trying to determine if in fact there is a violation."
There have been recent reports that Venezuela's state oil company PDVSA sent two shipments of gasoline to Iran last month.
The U.S. Congress passed sanctions last year that threaten to penalize foreign companies that do business with Iran.
