"I am not going to allow your my client to make me feel like it is any way my fault because it isn't".
Mueller told his own lawyer, Gabe McFarland, he purposefully closed his hand during the photo opportunity with Taylor, "so as to not poke" her. Swift counter-sued Mueller for just one dollar, to prove a point.
Swift is expected to testify.
Social media was also active during the court proceedings, with a majority positive reaction to the way Taylor Swift acquitted herself during her testimony and under cross-examination. I wasn't going to blame Greg Dent for something Mr Mueller did.
When the possibility was suggested that Mueller may not have been the person who groped her.
On Wednesday, Mueller testified that the photo-taking experience was "weird and awkward", but insisted he touched Swift's ribs, not her buttocks. Swift's bodyguard and Simbeck are listed as potential witnesses. She says she and Mueller started out as co-workers at country station KYGO and became romantically involved in February 2013.
To this Swift replied, "Your client could have taken a normal photo with me".
The trial centres on a photograph in which Taylor, the DJ and his then-girlfriend, Shannon Melcher, are seen smiling together backstage at the Pepsi Center.
The radio host, David Mueller, has sued the pop star, claiming she and her team's accusations against him caused him to lose his job and harmed his reputation. Swift countersued for assault and battery, and is asking for $1. He stayed on my bare a** cheek as I lurched away from him uncomfortably.
Taylor Swift faced her alleged assaulter in court as she told jurors that he deliberately groped her bottom during a fan meet-and-greet session. She testified she first mentioned the incident about 15 minutes later to her photographer Stephanie Simbeck.
However, Swift's attorney Doug Baldridge argued that the incident did happen and that Mueller was suing for fame and money.
"It was a definite grab, [a] very long grab", Swift, 27, said in court Thursday.
Andrea Swift also said that they did not report the alleged assault to the police out of privacy concerns.
Andrea Swift said she wanted to keep the encounter private because she didn't want it to define her daughter's life.
Mueller, 55, testified on Tuesday that he may have made innocent contact with Swift but denied any inappropriate behavior.
She dismissed attempts to dissuade her from her story and rejected the suggestion that she had continued greeting guests for as long as 30 minutes after the alleged assault, as if nothing had happened.
