“When you suffer from pathological disease, you’re not really getting better unless you start taking pills and things,” Trump said on Fox News’ “The O’Reilly Factor” on Friday.
 
“Do you think that’s the right temperament to be president? I don’t think so,” he added.
 
Trump added that the media investigation into Carson’s past is worthwhile and not just a witch hunt.
 
“I don’t think it’s small ball if you have somebody that admits that he suffers from pathological disease,” Trump said.
