Taylor Swift's lawsuit against a former Denver radio host who denied groping her hits federal court on Monday, with the charting-topping singer set to testify at the civil trial expected to run nine days in front of a jury of nine.
Ex-DJ David Mueller already has been sanctioned for destroying evidence.
Mueller had first charged in a lawsuit that Swift falsely accused him of touching her inappropriately during a photo he took with her and his girlfriend before Swift's 2013 concert at the Pepsi Center in Denver, The Daily Beast reported.
Mueller charged that Swift pressured the country radio station he worked for, KYGO, to fire him from his $150,000 disc jockey job.
Swift, who said the groping left her "shocked and distressed," then countersued and has aggressively pursued the case.
The Denver Post reported that security removed Mueller from the concert shortly after the meet-and-greet photo session and Swift’s manager Frank Bell told KYGO about the alleged incident.
TMZ posted the reported photo in question last November.
"Right as the moment came for us to pose for the photo, he (Mueller) took his hand and put it up my dress and grabbed onto my ass cheek, and no matter how much I scooted over, it was still there... it was not an accident," Swift said during a deposition, per The Daily Beast.
The Post said Taylor didn’t file charges with police at the time and the incident mostly flew under the radar until Mueller filed his lawsuit against the singer in September 2015, spurring Swift's countersuit.
U.S. District Judge William Martinez has already sanctioned Mueller for destroying four devices, including his computer and an iPhone, which held a recording he made with his boss the day after the incident with Swift, per The Daily Beast. Mueller was fired the day after the conversation.
