Presumptive GOP presidential nominee Donald Trump is optimistic about his chances of winning a general election match-up versus Hillary Clinton because she hasn’t been vetted before, spokeswoman Katrina Pierson said Wednesday. “Oh, absolutely,” Pierson said in response to a question about Trump’s enthusiasm for facing Clinton in November. “Mainly because Hillary Clinton has never been truly vetted before. Particularly by the media,” she said to MSNBC’s Tamron Hall. “How many times has Hillary Clinton been asked about the specific role in Benghazi outside of the testimony?” Pierson asked.
