MIAMI (AP) — Nicoás Maduro has named a powerful ally sanctioned by the U.S. as a drug kingpin along with a cousin of the late Hugo Chavez to revamp Venezuela's oil industry amid massive gasoline shortages.

Tareck El Aissami was appointed oil minister Monday and Asdrubal Chavez tapped to head of state-run oil giant PDVSA. The appointments were published in the official gazette. The government has yet to comment.

Both positions were occupied until now by Gen. Manuel Quevedo, who during his 28-month tenure watched as oil production in the country sitting atop the world’s largest petroleum reserves collapsed by 65%.

U.S. Immigration and Customs Enforcement recently added El Aissami to its list of 10 most-wanted fugitives. He was sanctioned in 2017 as allegedly being a major drug trafficker and then was indicted two years later on allegations of violating those sanctions.
