On Sunday, South Carolina Governor Nikki Haley deemed Chris Christie’s endorsement of Donald Trump incomprehensible and spent a fair amount of time trashing “bully” Trump.

“[N]one of us understands why he did this,” said Haley to Clinton lackey and ABC host George Stephanopoulos, referencing Christie’s endorsement of Trump.

Christie endorsed Trump on Friday, the day after Rubio clocked the real estate mogul in the Thursday night Republican presidential debate.

The popular female governor, who recently endorsed Florida Senator Marco Rubio, took Trump to task, comparing his behavior to that of an undisciplined kindergarten on the loose before rattling off his failed business ventures.

“Donald Trump is everything we hear and teach our kids not to do in kindergarten. And we have seen this behavior over and over again that’s unacceptable,” said Governor Haley. “And I think what we saw from Marco is exactly what we tell our children also: if a bully hits you, you hit back.”

Haley added that there are “a lot of questions that Donald Trump hasn’t answered,” highlighting his missing tax returns due to an audit; which does not stop someone from disclosing their returns.

“You look at all these issues, this is one more project that Donald Trump is doing. Trump University, Trump Vodka, Trump Airlines, Trump Mortgage — all failed projects,” added the governor. “This is one more project. And we’re really concerned about what that’s going to be.”

The ABC host asked Haley how a Trump nomination—which is seemingly looking more and more inevitable—would impact the Republican Party.

“Well, it’s scary. I mean, this is where we think these next few states matter, because it will start to ask him the questions and get the answers,” Haley answered. “We’re seeing a lot of things from Donald Trump with no answers. I’ve seen him talk about being for universal health care. I’ve seen him talk about wanting to do things and he’s not giving us the answers for it. So, I think what he’ll do to the Republican Party really makes us question who we are and what we’re about. And that’s something we don’t want to see happen.”

"Chris is a dear friend, but none of us understands why he did this.”

Stephanopoulos then asked Haley about Christie’s endorsement of Trump, to which Haley gave a simply reply: "Chris is a dear friend, but none of us understands why he did this.”

She added that she does not think Trump is as electable as many seem to believe. “It is impossible for him to win a general,” she emphatically stated, adding that “his cap is 35 [percent]” and his negatives are simply too high.
