Republican presidential candidate Donald Trump, brushing aside any recent claims of civility, has equated Ben Carson's childhood "pathological temper" to the illness of a child molester.

Trump also questioned Carson's religious awakening and berated voters who support him.

"How stupid are the people of the country to believe this crap?" said Trump.

For more than 90 minutes Thursday night, the billionaire real estate mogul harshly criticized not only Carson, but many of his other competitors in the race for the GOP nomination.

He called Marco Rubio "weak, like a baby."

The one candidate Trump did not go after was Chris Christie.
