Elon Musk took a jab at Donald Trump after his dud military parade sparked dozens of "No Kings" protests, hitting the president where it hurts most.

After Elon expressed regret for some of the tweets, the White House said Trump was thankful and "appreciative" of his apology — however, it sounds like he's certainly not forgiving or forgetting, as a source tells People the two remain on "so far from good terms."
