Donald Trump Says Mike Pence Won't Call Hillary Clinton Names

— -- Donald Trump acknowledged that he and his running mate Indiana Gov. Mike Pence have different styles, and that he doesn't necessarily expect Pence to use the name-calling tactics that Trump has used throughout the campaign.

"We're different people, I understand that," Trump said in a preview of a "60 Minutes" interview that the pair did together.

Trump used the example of how he calls Hillary Clinton "Crooked Hillary" as something that he doesn't expect or want Pence to do.

"He won't [call Clinton that name], I didn't ask him to do it but I don't think he should do it because its different for him," Trump said in the clip. The full interview will air Sunday night.

For his part, Pence chose not to directly comment on the tenor of Trump's campaign so far.

"I think this is a good man who's been talking about the issues the American people care about," Pence said in the clip.

"This campaign and Donald Trump's candidacy has been about the issues the American people care about. They see America in decline at home and abroad, they see our porous borders, a Congress that's unable to balance its budgets or deal with and end illegal immigration. They want a leader, they want leadership in Washington, D.C., that will solve problems and strengthen our country," he said.

Trump reportedly also revealed in the interview that part of the reason why he picked Pence as his running mate was in an effort to unify the party.

There had been speculation that Trump chose Pence over former Speaker of the House Newt Gingrich and New Jersey Gov. Chris Christie, both of whom were also in contention for the vice presidential slot, in order to make peace with the Republican establishment, but this is the first time Trump made that clear himself.

The revelation comes from Jeff Fager, the executive producer of CBS' "60 Minutes," where Trump and Pence gave their first sit-down interview as a presidential ticket. The interview will be aired in full Sunday night.
