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.

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.

Texas Attorney General Ken Paxton asked a state court Tuesday to hold former Rep. Beto O’Rourke in criminal contempt for raising money for Democratic lawmakers who are staying out of state, alleging O’Rourke violated a court order restricting his fundraising efforts—and making claims that O’Rourke’s lawyer has slammed as an “outright lie.”
