Vice President Mike Pence announced new sanctions on three Venezuelans on Monday, designating them as “narcotics kingpins” and restricting their financial and travel access in a swipe at the country’s authoritarian government.

Speaking in Washington to the Organization of American States, Pence also called for Venezuela to delay its upcoming presidential election — and for the organization to suspend Venezuela from its membership.

Pence said the Trump administration had targeted “three Venezuelans with direct ties to the [Venezuelan President Nicolás] Maduro regime” by freezing their assets and blocking their access to the U.S., “so they can no longer poison our people with their deadly drugs.”

The Treasury Department identified the individuals as Pedro Luis Martin Olivares, a former top official at Venezuela’s National Directorate of Intelligence and Prevention Services, and associates Walter Alexander Del Nogal Marquez and Mario Antonio Rodriguez Espinoza. It also designated 20 companies with ties to the three men in Venezuela and Panama.

The U.S. had previously sanctioned dozens of other Venezuelan officials.

Maduro has presided over a spiraling economic downturn and hyperinflation crisis, triggering widespread hunger and migration. And his increasingly repressive government came down hard on protests last summer, with the Associated Press’ count of the death toll surpassing 100.
