The story is the spy chip allegation saying China put spy chips on boards used in servers bought by Apple.

‘This did not happen,” Cook (pictured) told Buzzfeed News, “I feel they should retract their story. There is no truth in their story about Apple. They need to do that right thing.”

“I was involved in our response to this story from the beginning,” said Cook, “I personally talked to the Bloomberg reporters along with Bruce Sewell, who was then our general counsel. We were very clear with them that this did not happen, and answered all their questions.”

“Each time they brought this up to us, the story changed, and each time we investigated we found nothing,” added Cook.

Asked if it could have happened without him knowing about it, Cook said: “The likelihood of that is virtually zero.”

 Cook also said that Bloomberg did not supply any specific information about the alleged spy chips.

Apple appears to be set on a confrontation with Bloomberg over the story.

The boards’ manufacturer, Supermicro, lost $600 million in market cap when shares crashed after the Bloomberg story was published.
