FOX Nation host Abby Hornacek takes a closer look at the topics and buzz words you find your friends and coworkers using to sound intelligent. Each week Abby and her expert guests will tackle topics we take for granted and help to explain the roots and meanings behind them.

This week, FOX Senior Judicial Analyst, Judge Andrew Napolitano, joins Abby in the classroom to help with her lesson plan. Judge Napolitano explains FISA's history, why it's being reevaluated now, and what this legislation could mean for Americans.
