A Texas state bill could charge transgender people with “gender identity fraud,” making it illegal to identify as trans on official documents and potentially leading to jail time.

The bill, which was filed last week by Republican state Rep. Tom Oliverson, would make it a state jail felony if a person “knowingly makes a false or misleading verbal or written statement” by identifying their sex assigned at birth incorrectly to a governmental entity or to their employer. State jail felonies in Texas are punishable by up to two years in jail and a fine of up to $10,000.

Oliverson did not immediately return a request for comment.
