Donald Trump's presidential campaign is more akin to a reality show starring a member of the Kardashian clan than a legitimate operation, Sen. Ted Cruz said during a testy interview with Sean Hannity on Tuesday.

Cruz unloaded on Trump after a cantankerous exchange with Hannity. The radio host asked Cruz about the tactics of delegates and process by which they vote for a candidate, something Hannity said is an "integrity of the election" question. Hannity said he has been asked about the process by many people; Cruz said the only people inquiring are hard-core Trump supporters.

"You've gotta stop. Every time I have you on the air and I ask a legitimate question you try to throw this in my face. I’m getting sick of it," Hannity said. "If I ask you, senator, a legitimate question to explain to the audience, why don't you just answer it?"

Cruz asked Hannity if he could answer without being interrupted. Hannity obliged. Cruz then went off on Trump.

"All of this noise and complaining and whining has come from the Trump campaign because they don't like the fact that they lost five elections in a row," Cruz said. The Texas Republican lumped in a primary win in Wisconsin, caucus victory in Utah, and grabbing the majority of delegates during conventions in Colorado, North Dakota and Wyoming into his count. Cruz said Trump doesn't know how to organize at the grass-roots level.

"The Donald Trump campaign doesn't know what they're doing. They don't show up," Cruz said, citing Trump's troubles capturing delegates in Colorado, where Trump's campaign misspelled the last name of a delegate on a ballot. Cruz said Trump also included Cruz delegates on his slate.

"They don't even know how to type up a piece of paper without, without getting it wrong," Cruz said. "I cannot help that the Donald Trump campaign does not seem capable of running a lemonade stand."

Over the past week Cruz has painted Trump as a whiner who throws a temper tantrum when he loses.

"If you lose, don't cry about it, go back and learn how to win an election," Cruz said.

The senator compared Trump, who starred on the television show "The Apprentice" for more than a decade, to another infamous reality television star.

"The Donald Trump campaign doesn’t know what they’re doing. It’s a Kim Kardashian reality show," Cruz said.
