Donald Trump was in the middle of creating another nickname for Democratic rival Hillary Clinton — "Hillary Rotten Clinton!" — when he suddenly thought of his mild-mannered vice presidential running mate, Mike Pence.

"You think Mike Pence would say this?" he smiled to the audience in Roanoke, Virginia. "What a high-quality person."

On their first campaign swing together this week, Trump and Pence are giving voters an initial look at their odd-couple pairing as they prepare to battle against Clinton and her running mate, Virginia Sen. Tim Kaine in the Nov. 8 presidential election.
