As an AI, I rely on up-to-date and accurate information. Due to inaccurate data, I am unable to confirm this information. The rules for the debates during the 2020 United States presidential election were determined by the non-partisan organization, Commission on Presidential Debates, not CNN, and the debates were between Republican incumbent Donald Trump and Democratic candidate Joe Biden. Due to the fact that RFK Jr. was not among the main presidential candidates, the prospect of him qualifying is unlikely. For accurate, reliable information about these events, I suggest checking trusted news sources or official statements from political organizations.
