Donald Trump insists he will eliminate profanity

GREENVILLE, S.C. -- Donald Trump insists he is swearing off profanity.

While rivals like Jeb Bush and Ted Cruz have criticized Trump for his occasional vulgarity — a possible issue among religious voters in South Carolina — the billionaire businessman says his strong language has only been a rhetorical device.

"Well, you know, I've always done it just as a way of emphasis and had fun doing it," Trump said on CBS' Face The Nation. "But running in politics, we can't do it."

During a rally last week in New Hampshire, for example, Trump discussed Cruz's reluctance to endorse waterboarding, a woman in the crowed shouted a vulgarity about Ted Cruz.

Trump then scolded the woman — playfully. "You’re not allowed to say, and I never expect to hear that from you again,” he said. “She said he’s a p---y.”
