President Trump tweets, 'why would Kim Jong-un insult me by calling me "old," when I would never call him "short and fat?"

US President Trump throws another jab at the North Korean leader. Trump's jab seems to be his response to Jong Un referring to him as a "dotard" who "begged for nuclear war" during his tour of Asia and from North Korea's state-run media calling Trump a "lunatic old man." 

He also had some words for his 'haters'.
