It’s what’s being called the Ken Stoppers truck, and it's Sen. John Cornyn’s latest campaign against Ken Paxton, a new tactic to shine a light on any illegal activity they can find on the attorney general. What they're saying:On the side of each truck was a digital sign, asking the public to come forward with any knowledge of crimes committed by Ken Paxton. "We believe there are dozens and dozens of Texans who know something, who saw something, who heard something," says Matt Mackowiak, the senior advisor for Cornyn’s campaign. Mackowiak believes tales of illegal behavior from Paxton have gone untold across the state, and that’s what led them to create KenStoppers. The other side:Paxton’s office has not made an official statement on the KenStoppers campaign but in recent weeks, Paxton has been very vocal against Cornyn.
