Making the Case, How to Be Your Own Best Advocate by Kimberly Guilfoyle. I recommend this book. Kimberly Guilfoyle is a smart, successful woman who works for FOX. According to report, Donald Trump wanted her to work for him in the White House, but she turned him down. Now she may replace Sean Spicer. She was smart enough to turn Trump down once. Will she do it again? My question is since she is so smart, why is she working at FOX?
