Allegations about Horner's conduct were first revealed by Dutch publication De Telegraaf, and since then the Red Bull team principal has vowed to clear his name.
Jordan knows what it takes to manage a successful team, and he has had some pretty strong words about the way in which the allegations have been handled.
“I have experienced many wrong decisions," he told F1-Insider.com.
"But the Red Bull situation is the most absurd thing I've ever seen. Of course, there is initially the presumption of innocence for Horner. But does anyone seriously believe that the employee made up her mind about the allegations?
"If Horner is innocent, is she guilty? Red Bull's loss of image is already huge. Someone has to pull the ripcord now.”
