Dallas County District Attorney John Creuzot and two other Democratic district attorneys filed a lawsuit Friday challenging the constitutionality of Texas Attorney General Ken Paxton’s newly adopted rules targeting urban prosecutors.

The DAs say in two lawsuits that a new rule requiring counties to hand over almost all documents the attorney general’s office requests violates state and federal law.

Last month, it became a requirement for district and county attorneys that represent an area with a population of more than 400,000 people to provide “performance reports" to Attorney General Ken Paxton's office and provide certain case files.
