Why didn't he issue the ad in the early days of Trump's presidency when this happened?
Asking for a friend
He spoke out publically but no one was making ads. He did not issue this ad. People knew what he was saying in public since his son's death and used his comments for their ad.
All I know is this...this is the first I heard of it, in an ad or otherwise
Was Don Lemmon or Madcow ranting about what he spoke out publicly about?
The father, a retired police detective, and veteran refused to meet with Trump in Dover when his son's remains were returned. He called for a full investigation of the incident that took his SEAL Team 6 son's life. That was in Feb 2017. His refusal of a meeting and call for an investigation was widely covered in media.
