Cruz did not answer Cuomo's charge, but rather attacked his interviewing style in response.
You actually wonder why you don't have a lot of Republicans that want to come on your show. You scream at me and yell at me and insult me.
While Cruz has generally supported Trump as Texas senator, the two have a rocky history.
Trump would frequently refer to Cruz as "lyin' Ted" during the 2016 primaries. He also called him a "maniac" and a "hypocrite" and suggested that he wasn't qualified to run for president because he was born in Canada.
Cruz, in turn, referred to Trump as "weak" and the "Twitterer-in-chief" and accused him of having ties to the Mafia.
That very personal feud is apparently now just water under the bridge.
