The Department of Justice told the governors of Maine and California on Thursday that it was investigating their housing of transgender women in women’s prisons, to assess whether the constitutional rights of other prisoners at the facilities had been violated.

Federal officials said they would investigate “allegations of sexual assaults, rape, voyeurism and a pervasive climate of sexual intimidation due to the presence of males” in women’s prisons in California. In Maine, they said, they were responding to allegations that “a biological male” remained housed with women despite complaints that the inmate had assaulted or harassed female inmates.

“Keeping men out of women’s prisons is not only common sense — it’s a matter of safety and constitutional rights,” Attorney General Pam Bondi said in a news release on Thursday. “The Trump administration will not stand by if governors are facilitating the abuse of biological women under the guise of inclusion.”

The state inquiries are the latest moves by the Trump administration to force prisons to house transgender women with men, in compliance with President Trump’s executive order last year “defending women from gender ideology extremism and restoring biological truth.”

The order pledged to “ensure that males are not detained in women’s prisons,” one response to what it called “an ongoing and purposeful attack against the ordinary and longstanding use and understanding of biological and scientific terms, replacing the immutable biological reality of sex with an internal, fluid, and subjective sense of self unmoored from biological facts.”

Some affected federal prisoners sued the government over the new policies, arguing that housing them with men could make them targets of violence and increases their risk of suicide. Federal courts blocked those prisoners from being moved to men’s housing last year; the federal government is appealing the ruling.
