WASHINGTON (Reuters) - White House trade adviser Peter Navarro said on Thursday that United States efforts to cut off Iran’s oil export revenues through sanctions are succeeding.

“What we’re trying to do here, which is succeeding, is to cut off their export revenues. They sell oil, they sell petrochemiclas, they sell iron and steel,” Navarro said in an interview with Fox News. “It’s certainly working - it’s working beautifully.”
