The recent Twitter war between Republican hopefuls Donald Trump and Ted Cruz has some calling them children. After Cruz retweeted a meme condemning Trump’s wife Melania in a racy pic, Trump fired back with an unflattering picture of Cruz’s wife Heidi, thus kicking off a battle you wouldn’t believe happened between two individuals vying for president were this any other year.

Anderson Cooper brought up the heated exchange during CNN’s Town Hall on Tuesday night and Trump, unsurprisingly, defended his actions. "I thought it was a nice picture of Heidi," he said, according to Variety.

Cooper, however, was not having it. "Come on, you’re running for president of the United States," he responded.

"Look, I didn’t start it," Trump fired back, refusing to back down.

That’s when a firm Cooper tried to set Trump straight. "Sir, with all due respect, that’s the argument of a five-year-old," he said.

Trump, of course, responded like any toddler caught red-handed would. "It is not!" he argued. He also maintained that Cruz was somehow responsible for all of this, because it definitely does not take two to argue. See how it all went down below.
