John of Salisbury , who was a secretary for Theobald , added information about <unk> in a letter to Alexander III on unrelated business . In the section of the letter , John pointed out to the pope that no matter what others might say about <unk> , he had failed to secure other clergy willing to <unk> that he was innocent .
