Dr. Jim Sears, a co-host of the CBS show The Doctors, has warned that transgender girl Coy Mathis might walk around the girls' bathroom with her genitals exposed.

Sears, a pediatrician, made his remarks during an appearance on CNN Newsroom.

Mathis is the 6-year-old transgender girl who has been barred from using the girls' bathroom at her elementary school. The Transgender Legal Defense & Education Fund (TLDEF) filed a complaint with the Colorado Civil Rights Division after Mathis' parents, Jeremy and Kathryn Mathis, were told in mid-December by the Fountain-Fort Carson School District 8 that she could no longer use the girls' bathrooms that she had been using for the past year at Eagleside Elementary School in Fountain, where she is a first-grader. Mathis is currently being home-schooled until the situation is resolved.

“I have three kids, a daughter and two boys, and as when my daughter was that age, I would have been very uncomfortable if there was a boy with a penis walking around their bathroom,” Sears said on Wednesday's show. “And you say that the stalls are private. You know, at that age, most boys especially will use the bathroom then leave their pants down while they walk to the sink to wash their hands and then pull it up. So it's going to be very uncomfortable for the other girls seeing a penis in their bathroom.”

The other panelists on the segment expressed support for Mathis' position and appeared outraged by Sears' insistence on describing Mathis as a boy.
