Raddatz noted to Cruz that Trump has signaled he may not fulfill certain campaign promises like fully repealing Obamacare and pulling out of the Paris climate agreement. She asked Cruz if Trump's change in tone concerned him.
Cruz said that he will work with Trump before warning Republicans that they must bring change.
"If we’re given the White House and both houses of Congress and we don’t deliver, I think there will be pitchforks and torches in the streets,” he said. “And I think quite rightly. I think people are so fed up with Washington. This election was a mandate with change, and the most catastrophic thing Republicans could do is go back to business as usual.”
