The Trump administration on Monday responded to a report that it seeks to roll back protections for transgender people by citing a 2016 court ruling that struck down an Obama-era rule that defined sex as binding precedent that it will follow.

The New York Times reported on Sunday that Health and Human Services sent a memo to government agencies that adopts a narrower definition of gender that essentially eliminates protections for transgender people granted during the Obama administration. The memo said that gender should be defined as male or female at birth and is immutable.
