Just a few days after Donald Trump accused Carly Fiorina of "interrupting everybody" during the fourth Republican presidential debate in Milwaukee, the former Hewlett-Packard CEO has pushed back at the GOP front-runner. Fiorina did not respond at the forum, but in a Facebook post Thursday, she slighted the billionaire, telling him that money cannot buy smarts.

"Donald, sorry, I've got to interrupt again," Fiorina wrote. "You would know something about pathological. How was that meeting with Putin? Or Wharton? Or your self funded campaign? Anyone can turn a multi-million dollar inheritance into more money, but all the money in the world won't make you as smart as Ben Carson."

Fiorina was referring to a comment Trump made earlier Thursday, when he said that retired neurosurgeon Ben Carson's "pathological temper" is incurable.

"It's in the book that he's got a pathological temper," Trump said on CNN's "Erin Burnett OutFront" about Carson's autobiography. "That's a big problem because you don't cure that ... as an example: child molesting. You don't cure these people. You don't cure a child molester. There's no cure for it. Pathological, there's no cure for that."

In his 1980 autobiography, Carson said the root of his violent behavior in his youth was a "pathological temper." He detailed in the book how he overcame these tendencies. 

Trump reiterated concerns about Carson's "pathological disease" while at a rally Thursday evening in Fort Dodge, Iowa.

"Carson is an enigma to me," Trump said. "He said that he's 'pathological' and that he's got, basically, pathological disease. ... I don't want a person that's got pathological disease."

The former reality star also questioned Carson's success in polls surveying Republicans likely to vote in the Iowa caucuses, the Washington Post reported.

"How stupid are the people of Iowa?" Trump asked Iowa supporters Thursday. "How stupid are the people of the country to believe this crap?"

Trump has not yet responded to Fiorina's remark.
