Truns out, this headline is another CNN lie.

CNN:
Secret Service spoke to Trump campaign about 2nd Amendment comment  —  (CNN)A US Secret Service official confirms to CNN that the USSS has spoken to the Trump campaign regarding his Second Amendment comments.  —  “There has been more than one conversation” on the topic, the official told CNN.
 
Editor's note:  No such discussion took place per the Service and the Trump campaign.  But,  expect the major/Marxist media to continue this story.  If true,  it would indicate tthat the Service considered Trump an existential threat to Clinton.  The Service does not see such a threat.
