Paxton also used the letter to further condemn what he called the "Biden-Harris administration's open border policies," saying that Texas has "ballooning noncitizen populations" that he suggested the county's voter registration mailer efforts would target.

Attorney General Ken Paxton and Secretary of State Jane Nelson are targeted in the new suit, escalating a pre-election war over voter registration efforts.

Paxton's office withdrew a 2016 opinion ruling government entities — like Dallas — are not liable when private businesses ban guns on government-leased property.

With less than a month to go until the deadline to register to vote in Texas, Attorney General Ken Paxton continues to target the issue of voter registration while civil rights groups express concern over the potential impact of his efforts.

Jolt, which advocates for more Latino voting participation, says the attorney general’s probe has spurred threatening comments online.
