Sen. John Cornyn (R-TX) suggested he will be skipping a midterm convention in September that amounts to a pep rally for his successful primary rival, Texas Attorney General Ken Paxton.

“I may have a conflict,” Cornyn said wryly when asked if he would travel to the event, to be held for all GOP Senate nominees running for election this fall. The event is being hosted in Cornyn’s home state of Texas, making his deflection a sign of further enmity between the two men.
