Two days later, he was sacked from KYGO - and two years later, he sued Swift claiming what he asserts was a false accusation caused him to lose his $150,000 a year job. He filed his suit against Swift in September of 2015, setting off the chain of events leading to the upcoming trial at which both Mueller and the singer are expected to testify. After Mueller's employer was informed of Swift's accusation, he was terminated from his job.
Swift is countersuing, claiming sexual assault.
One juror was dismissed over his answer tom the question, "In a lawsuit between David Mueller and Taylor Swift would you have bias for or against either Taylor Swift or David Mueller?". Swift in a way she found inappropriate, it was inadvertent as he rushed to get into position for the photograph, which, though inconclusive, is expected to be key evidence at the trial.
The nine-day hearing, at Denver's Alfred A. Arraj courthouse, will be presided over by US District Judge William Martinez. The pair met Swift during a backstage meet and greet. Swift knows exactly who committed the assault - it was Mueller - and she is not confused in the slightest about whether her long-term business acquaintance, Mr. Haskell, was the culprit.
"He 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", Swift said in court documents.
Entertainment news outlet TMZ obtained and published the photo, which has since been sealed by the court.
Mueller says he was verbally abused and kicked out of the venue by her security.
At the time of the alleged incident, Mueller was a radio DJ for country music station 98.5 KYGO in Denver on the Ryno and Jackson morning show, going by "Jackson". "It was not an accident, it was completely intentional, and I have never been so sure of anything in my life".
Swift countersued, alleging sexual assault by Mueller.
Mueller also accused his boss, Eddie Haskell, of being the one who had touched the singer inappropriately.
Taylor Swift is in federal court in Denver for the start of jury selection in her lawsuit against Denver disc jockey David Mueller involving a groping allegation.
But she does have to be present for the rest of the trial and is expected to testify.
Both Swift and her mother, Andrea Swift - who's also named as a defendant in the case - will testify at some point during the trial, according to the final pretrial order.
Swift fans can technically be allowed in the courtroom, as 32 seats are designated for members of the public - not media - and 75 seats will be made available in the public overflow location in the courthouse.
