Red Bull team principal Christian Horner has backed the United States Grand Prix stewards over the penalty given to McLaren's Lando Norris after his battle with Formula 1 title rival Max Verstappen, calling it a "black-and-white" case.
Norris was fighting for the final podium position at the Circuit of the Americas when he made an overtake around the outside at Turn 12, which Verstappen defended robustly and, with both cars leaving the circuit and continuing, the British driver kept hold of the position.
