Former government teacher Sharon McMahon appeared on The Daily Show with Trevor Noah on Monday, sharing why she started her fact-based Instagram account @sharonsaysso and explaining how she separates fact from conspiracy, breaking down the difference between a lie and bias.

The Duluth News Tribune reports McMahon was president of the political science association at the University of Minnesota Duluth. She taught in St. Paul, the San Francisco Bay area and a Maryland suburb of D.C. before returning to Duluth.
