Sara Tracy sent a message to W. Craig Jelinek - President and Chief Executive Officer of Costco Wholesale Corporation email address that said:
I recently sent a message asking if it was true that Costco advertises with Breitbart. I then called Costco, which I should have done first, to check out that information. I was told by Costco Marketing that the claim that Costco advertises with Breitbart is FALSE, a HOAX. I am writing to let you know I have that information and am very relieved that Costco has NO association with Breitbart. I am sorry that false rumors are being circulated about Costco. I have posted that on my Facebook page and taken down the false post that was sent to me.
