In an interview on Tuesday, Jeb Bush called Donald Trump a "junkyard dog" and said the businessman is not a conservative.
"He's a junkyard dog, that's for sure," the presidential candidate and former Florida governor said on NewsMax Prime. "I seem to be the target of most of his attacks. I don't know why he's so worried about me, maybe he thinks that I'm a real threat to him, cause I am. I'm the only guy that has taken him on."
While Bush has been out front in criticizing Trump, his fellow presidential candidates Ted Cruz and Rand Paul have also taken shots at Trump as the Iowa Caucus and New Hampshire primary draw near.
"There's nothing in his record that suggests to me that he's a conservative," added Bush, noting Trump's donations to Democrats, his past support for gun control and abortion rights, and support of eminent domain.
"He's gone bankrupt four times and says that's a victory when in fact it's a loss for his own equity investment, but more importantly, for all the employees that lost their jobs and the vendors that lost their business. So this is a guy that is not a conservative. He's an incredible personality, don't get me wrong. He's an incredible, he fills the space, and he's captured this sense of frustration that people have about Washington."
Bush said people should support him because of his record of being a "committed conservative," while Trump was "Johnny come lately."
