The Justice Department opened a third federal civil rights investigation Tuesday into a state housing men who identify as transgender in women’s prisons, this time targeting Washington state over allegations that female inmates were exposed to sexual violence and intimidation at a women’s correctional facility near Tacoma.

In a letter sent to Gov. Bob Ferguson (D), the DOJ announced it would investigate whether the Washington Corrections Center for Women in Gig Harbor engaged in a “pattern or practice” of violating the constitutional rights of female inmates by housing men who identify as women in the facility.
