Trump: 'I have best temperament to be president'

VIDEO: Trump: With SC primary win, he'll 'run the tables'

MOUNT PLEASANT, SC (WCSC) - Republican presidential hopeful Donald Trump criticized Gov. Nikki Haley, talked about the gun violence at Mother Emanuel AME last summer and defended his temperament to be Commander-in-Chief during a Lowcountry campaign stop.

Trump is riding high after a new national poll puts him  high above the pack.

On the South Carolina Republican primary, which Trump calls "very important," he said he does not think his numbers will be hurt by Haley's decision to back Sen. Marco Rubio.

In fact, he says he doesn't think endorsements mean that much. He was also quick to point out a new poll has him with a big lead nationally.

"But if we can do something really great here, which I love, you know I've been here so often, so much, I come to South Carolina," Trump said. "I love it. I love the people. If we can do something special here, we're gonna run the tables."

Trump says he gave Haley a lot of money through the Republican Governor's Association, but never asked for an endorsement and does not like her position on securing the border.

"Look, she's weak on immigration, very, very weak on immigration, and I'm very strong," Trump said. "Somebody wants to have people pour over the border, they're not gonna vote for me, anyway."

On the subject of gun violence, like that seen last summer when nine parishioners of Mother Emanuel AME Church were gunned down, Trump said it's not really a gun problem.

"I'm a very big Second Amendment person," he said. "I have to tell you, there's a huge mental health problem we have, which we don't discuss. That was a mental health problem."

As for the people who say they think Trump lacks the temperament to be Commander-in-Chief, claiming he is too quick to anger to have his finger on the nuclear button?

"We need toughness," Trump said. "We need toughness, Bill! Bill, we have people having their heads chopped off. We have people being drowned in cages, and we're worried about water boarding. Okay. I have the best temperament there is."

The Republican Primary is on Saturday. Polls open at 7 a.m. and close at 7 p.m.
