Super Hit's new owners sued Ann Romney, her trainers and her vet. The case was settled out of court last September. The Romney campaign called the case "frivolous," but refused to allow the LA Times to interview the Romneys, their trainers, or their vet. The LA Times also reports that Romney's lawyers have sought to keep the case out of the public eye by trying to get the attorney of Super Hit's new owners to sign a confidentiality agreement.
The Romneys continue their relationship with the same trainers under whom Super Hit was given a staggering amount of painkillers so that he could be forced to continue performing.
