The concerns arise weeks after a U.S. military action that removed Venezuelan President Nicolás Maduro from power. This operation transferred control of Venezuelan oil flows to U.S. oversight, a change Rubio has claimed is part of a stabilization effort. Trump has stated that the United States is taking Venezuelan oil and processing it through U.S. refineries. It aims to redirect oil revenue away from Maduro’s network to advance U.S. goals in Venezuela. In addition to the oil revenue, senators have criticized how the administration has conducted briefings and oversight since the operation against Maduro.
