On the 30 January 2013 edition of CBS This Morning, Nancy Cordes falsely characterized the weapon used in the 2011 mass shooting in Tucson, Arizona. Cordes noted that astronaut Mark Kelly, "whose wife...Gabrielle Giffords was badly injured in the Tucson shooting," would call for a ban on "assault weapons like the one that was used to wound his wife and kill six others."

However, Jared Loughner, the perpetrator of the massacre, used a Glock 19 handgun with a 33-round magazine, not the military-style, semi-automatic rifles that are often labeled "assault weapons" by gun control supporters. The journalist even showed a photo of the firearm in question as she misrepresented its type.
