(CNSNews.com) - "What Happened," Hillary Clinton's new book about the 2016 presidential race, is due to hit store shelves in a few weeks, but even before the ink is dry, MSNBC has obtained exclusive audio clips of Clinton explaining some of the highs and lows.
For example, how did Clinton feel at the second presidential debate in St. Louis, when Donald Trump stood several feet behind her as she answered a question?
"'This is not okay,' I thought. It was the second presidential debate and Donald Trump was looming behind me. Two days before, the world heard him brag about groping women. Now we were on a small stage, and no matter where I walked, he followed me closely staring at me, making faces.
"It was incredibly uncomfortable. He was literally breathing down my neck. My skin crawled."
Clinton said she wished she could hit pause and ask everyone whether she should keep calm and carry on -- as if Trup weren't invading her space.
"Or do you turn, look him in the eye,and say loudly and clearly, 'Back up, you creep. Get away from me. I know you love to intimidate women, but you can't intimidate me, so back up!'"
Clinton said she chose option A --"aided by a lifetime of dealing with difficult men trying to throw me off. I did, however, grip the microphone extra hard," she said.
Clinton mulled whether she should have chosen option B.
"Maybe I have overlearned the lesson of staying calm, biting my tongue, digging my fingernails into a clenched fist, smiling all the while, determined to present a composed face to the world."
Clinton said the book is her attempt to "pull back the curtain on an experience that was "exhiliarating, joyful, humbling, infuriating and just plain baffling."
Said writing it wasn't easy. She admits she let down millions of people who were counting on her: "I couldn't get the job done, and I'll have to live with that for the rest of my life," she wrote.
