Speaking to Red Bull's ServusTV channel about the Horner situation, Marko said that the length of the investigation is not the fault of Red Bull themselves: "As you know, this is an internal investigation," he said.
"The sooner a result is available, the better because of course, rumours and other stories are bound to sprout due to the long duration.
"[But] I think Red Bull has reacted very well in this matter. The long duration of this investigation is not their fault. They are endeavouring to [have] a fair investigation and then react accordingly."
