US Energy Secretary Chris Wright said that he is unaware of any operation to take millions of barrels of crude oil from Iran, distancing himself from assertions made by President Trump, according to multiple media reports on Wednesday.
Wright said he was not aware of such an initiative, though he acknowledged that the US military had facilitated the transit of oil through the Strait of Hormuz.
His remarks follow claims by Trump that the US has secretly extracted large volumes of Iranian oil.
The US President said he had ordered a "secret mission" involving the US military to support commercial vessels through the Strait of Hormuz, an operation that enabled over 100 million barrels of crude to transit the key chokepoint into global markets.
Trump said, in a social media post, that more than 200 commercial vessels had transited the Hormuz under the protection of the operation, which he said was launched last month.
"This wildly successful effort is because the United States of America controls the Strait of Hormuz - not Iran," the US President said. Trump did not provide operational details of the mission or evidence supporting the figures cited.
