The Chinese spy balloon that was shot down over the Atlantic Ocean in early February was built -- at least partly -- using American off-the-shelf parts, a U.S. official has confirmed to ABC News.
A second U.S. official was also able to confirm that the balloon did not appear to have transmitted any of the data it collected on its journey above North America, as was initially reported by the Wall Street Journal.
The first official could not say whether any of the American gear was sold illicitly to China but said determining whether any of it came from illegal trade was a topic of serious concern among officials since some items -- like chips -- are forbidden to sell to certain markets.
