“He and I agree on most things, particularly when it comes to substance,” Cornyn said.

Cornyn said he and Cruz work together on a regular basis, but they’ve had “differences on tactics” or how to accomplish goals, he told KERA.

“Part of it [is] from the fact that I’ve been here a while and I’m part of the elected Republican leadership,” Cornyn said. “My goal has always been to figure out how we can advance the conservative cause.”

“I think he’s taken the more immediate shorter-term view of things,” Cornyn continued. “Clearly, he didn’t come here to remain in the Senate. He came here to run for president. I think that perhaps explains the difference in tactics.”
