DES MOINES, Iowa (AP) — University of Iowa athletic director Gary Barta has testified that three rounds of complaints from parents and field hockey players prompted an investigation into the program that led to the firing of coach Tracey Griesbaum in 2014.

Griesbaum’s termination is a central piece of a lawsuit filed by former administrator Jane Meyer against the university and was a focus Monday in testimony in Meyer’s discrimination trial. Meyer, who was Barta’s longtime top assistant, filed the suit after being moved to another department soon after the firing of Griesbaum, who was her partner. Meyer’s job was eliminated in 2016.

Meyer alleges she suffered workplace discrimination as a gay woman in a relationship with a coach, that the school retaliated against her and that she was paid less than a male counterpart.
