Russia expert Fiona Hill captured national attention two years ago when she testified during then-President Donald Trump's first impeachment hearing. Now she's out with a new book, "There Is Nothing for You Here: Finding Opportunity in the 21st Century." She joins Judy Woodruff to discuss her career as a presidential advisor and why she fears the U.S. is going down a dangerous path.
