Texas Attorney General Ken Paxton on Tuesday said prison is on the line for former Democratic Rep. Beto O’Rourke after he was accused of violating a court order blocking him from funding Democratic lawmakers seeking to thwart the GOP’s redistricting plan.

Paxton sued O’Rourke and his political group, Powered by People, last week, arguing that the group was deceptively fundraising for and illegally supporting Texas Democrats’ walkout.

Beto O’Rourke on Tuesday called Ken Paxton a “corrupt, lying thug,” after the attorney general said O’Rourke should be “locked up” for defying a judge’s order.
