Fox News host Greg Gutfeld challenged liberal co-host Jessica Tarlov on “The Five” over transgender issues in a near-shouting match Wednesday while discussing a convention for women in tech that was overrun by “non-binary” men.

A number of men gained admittance to the conference by labeling themselves as “non-binary,” prompting the company’s Chief Impact Officer, Cullen White, to scold the men from the stage of the Grace Hopper Conference Sept. 27. The conference is intended to help women seeking careers in technology, according to AnitaB.org.

“Simply put, some of you lied when you registered,” White told the men. “And as evidenced by the stacks and stacks of resumes you’re passing out, you did so because you thought you could come here and take space to try and get a job.”
