Swift, who was 23 at the time, has filed a countersuit in which she accused Mueller of "reaching under her dress and grabbing her bottom" as they posed for the photo. It was intentional. He stayed latched on to my bare ass cheek.
"I'm not going to allow you or your client to make me feel in anyway that this is my fault because it isn't", the singer continued, before saying, "I am being blamed for the unfortunate events of his life that are a product of his decisions and not mine". "A very long grab", she said at one point.
In 2015, Mueller sued Swift, claiming the false accusations had cost him his job.
Swift's assistants testified in depositions that as soon as the photo session ended, the singer told everyone in the room about the incident.
Swift got a laugh from people in the courtroom when she said her security guard, Greg Dent, saw Mueller "lift my skirt" but someone would have had to have been underneath her to see the actual groping - "and we didn't have anyone positioned there".
Swift's team told KYGO, a CNN affiliate, about the incident, and Mueller, then 51, was sacked two days later.
The station's program manager Herschel Coomer - known in the industry by the pseudonym Eddie Haskell - testified that Mueller was adamant he hadn't done anything improper.

Liddicoat was in attendance for all the meet-and-greets on June 2, 2013, and recalls Swift briefly talking with Mueller before the photo - though she doesn't know what was discussed.
He said he asked the employer of David Mueller, a former disc jockey accused of grabbing Swift, to investigate the allegation involving a photo op before a 2013 concert.
Swift said she did not need the photo to remember Mueller.
Call said he fired the DJ because of his shifting accounts of the incident, and because the photo showed that Mueller's hand was "not where it was supposed to be". He has also told the jury that his girlfriend was present at the photo shoot and that he would not touch another woman in a sexual way in her presence.
He noted that Mueller has said he lost an audio recording of a meeting he had with his bosses at country music station KYGO before they fired him.

Mueller testified Wednesday that the photo taken before the concert was "weird and awkward", but he insisted that he touched Swift in the ribs, not in the rear.
