HOUSTON — Employees at the Texas Department of Public Safety in June received a sweeping request from Republican Attorney General Ken Paxton’s office: to compile a list of individuals who had changed their gender on their Texas driver’s licenses and other department records during the past two years.

“Need total number of changes from male to female and female to male for the last 24 months, broken down by month,” the chief of the DPS driver license division emailed colleagues in the department on June 30, according to a copy of a message obtained by The Washington Post through a public records request. “We won’t need DL/ID numbers at first but may need to have them later if we are required to manually look up documents.”

After more than 16,000 such instances were identified, DPS officials determined that a manual search would be needed to determine the reason for the changes, DPS spokesperson Travis Considine told The Post in response to questions.
