President Donald Trump’s administration has proposed a rule change that would allow homeless shelters to deny transgender people equal access to services.

The Department of Housing and Urban Development proposal is focused on the Equal Access Rule, first published in 2012 to “ensure shelters and programs do not discriminate on the basis of sexual orientation or gender identity,” the National Center for Transgender Equality said Wednesday in a press release calling attention to the proposal.

HUD Secretary Ben Carson told House lawmakers this week HUD was “not currently anticipating changing the rule.”

“He lied,” the advocacy group said on Twitter.

HUD’s proposed change, published this spring, would allow shelter providers to consider “an individual’s sex for the purposes of determining accommodation within such shelters and for purposes of determining sex for admission to any facility.” Providers can consider “privacy, safety, practical concerns, religious beliefs” when making a determination about an individual’s sex, the proposed rule says.
