DENVER — A former radio DJ accused of groping Taylor Swift told a federal court on Tuesday that he may have touched the pop star's ribs. <br /> <br />Swift claims David Mueller touched her behind during a photo op before she played a show in Denver four years ago. <br /> <br />Lawyers for Mueller argue that a photo of the DJ and his former girlfriend posing with Swift on June 2, 2013, prove that he did not grope her, the Associated Press reported. <br /> <br />Lawyers for Swift, however, argue that the photo in fact provides damning evidence that he did. <br /> <br />Mueller is suing Swift for $3 million in lost earnings after he was fired from his $150,000-a-year radio job in the wake of the incident. <br /> <br />Swift is counter-suing for the token amount of $1, saying she wants to serve as an example to other women in similar situations.
