If one of the experts interviewed in the Mother Jones article published a study in JAMA (The Journal of the American Medical Association) documenting for the first time the effect that handguns have on youth mortality rates, only the JAMA article would be considered primary research.
A secondary source interprets and analyzes primary sources. These sources are one or more steps removed from the event.
