Sen. Tom Cotton, R-Ark., is trying to shut down President Joe Biden’s male-to-female prison pipeline before it starts. As The Federalist recently reported, the president plans to house federal prisoners according to their “gender identity” rather than by their biological sex. Now, the Arkansas Republican has introduced a bill that would require prisoners to be housed according to biological sex, rather than subjective claims of “gender identity.”

The senator told The Federalist: President Biden’s plan to house male and female prisoners together will put women in danger. Documented cases prove that placing men — including ones who ‘identify’ as female — in women’s prisons puts female inmates at increased risk of sexual assault. My bill will stop the president’s ill-conceived plan and keep men and women separated in federal prison.

Biden’s draft executive order, which was obtained by The Federalist, requires the U.S. attorney general to “within 30 days of the date of this order, begin the process of identifying any necessary changes to the [Bureau of Prisons] Transgender Offender Manual … to enable BOP to designate individuals to facilities in accordance with their gender identity.”
