When the Pentagon announced a $620 million loan last year to a small North Carolina startup linked to Donald Trump Jr., defense officials and the company tried to tamp down suspicions of cronyism.

The president’s eldest son said through a spokesperson that he wasn’t involved. The Pentagon said Trump Jr. played no role in the record-setting deal. And the startup’s founder told reporters that his company, Vulcan Elements, received no political favoritism.

But interviews and Defense Department records reviewed by ProPublica show that the request to loan hundreds of millions of dollars to the firm linked to Trump Jr. was made by Peter Navarro, a White House adviser to President Donald Trump and a friend of Trump Jr.’s.

Of the dozens of companies the Pentagon was considering funding at the time, Vulcan’s was the only deal initiated by a top aide to the president, said an official at the Pentagon who was not authorized to speak publicly.

After defense officials got the White House request, they asked Pentagon staff to move at an unusually rapid pace, said another person who was involved in the deal at the Pentagon but not authorized to speak about it. The staff worked late nights and with little sleep to get the loan through in a matter of weeks, the source said.
