After Donald Trumped accused Ted Cruz of being the “strongest” supporter of John Roberts’ Supreme Court nomination, Cruz shot back, “You know, Donald has a tenuous relationship with the truth.”

“I wrote one op-ped supporting President Bush’s nomination after he made it,” Cruz continued. “I would not have made that nomination.”

Trump then began trying to interject, spurring Cruz to suggest he “breathe, breathe.”

“When they’re done with the yoga, can I answer a question,” Rubio joked in response.
