A Republican district attorney in West Texas has opened a criminal investigation into pamphlets mailed to homes across Texas purporting to come from a transgender rights organization.

Sarah Stogner, district attorney for Loving, Reeves and Ward counties west of Odessa, told The Texas Tribune that her office is investigating the mailers as a potential forgery but said the scope could expand as new information comes in. Forgery is a state jail felony under Texas law.

Stogner said she felt the mailers — which were marketed as a resource guide for LGBTQ+ students from the Texas Transgender Student Union, a group recently formed in Wyoming — were an obvious bid to agitate voters ahead of the November midterm elections.

“If this ends up being legal, it is everything that is wrong with our current political climate,” Stogner said.

The origin of the mailers is currently unknown, Stogner said. The student union listed as the sender was formed as a limited liability company in Wyoming in September, records show. The group’s address on the mailer was listed as a Houston-area post office box.
