WATCH: National Women’s Law Center president will not define ‘woman’

She was asked repeatedly to provide a definition for 'woman' by US House Representative Andrew Clyde.

"Since you're the president of the National Women's Law Center, I was hoping that you could define what a woman is for us in this committee hearing," he said.

Goss-Graves did not provide a definition but said, "What I'll tell you is, I am a woman. That's how I identify."

She continued, "I wonder, however, if in part, the reason that you're asking the question is that you're trying to suggest.." but she was interrupted by the representative.

"I simply want an answer," Clyde insisted.

Goss-Graves then started speaking about people who identify as non-binary. Clyde again interjected, saying "Okay. We’re not going to go there."

"I was hoping maybe you would say something that maybe we learned in high school biology," he said. "It has to do with X and Y chromosomes…which define male and female, but I guess we're not going to get there."

Goss-Graves's gaffe comes after the National Women's Law Center claimed on Twitter the backlash against Lia Thomas to compete—and win—against women is misogyny. Those who oppose Thomas being in pool swimming against women are misogynistic against women, the organization said.

Thomas, a biological male, became the first transgender athlete to win an NCAA championship in March, taking home the 500-meter freestyle. Thomas finished fifth in the 200 freestyle and eighth in the 100 free at NCAA championships.

Before transitioning in 2019, Thomas competed on the men's team during Thomas's first three years at Penn.

The question of "what is a woman" has been focal point during the Biden administration's time in office. During her Supreme Court confirmation hearings, Justice Ketanji Brown Jackson refused to define the word woman.

"I’m not a biologist,” Jackson said in response to the question.
