Musk energizes Trump supporters at Butler rally, 3 months after assassination attempt on former president

Tesla CEO Elon Musk made a memorable appearance at former President Trump's campaign rally in Butler, Pennsylvania, on Saturday – a rare appearance for the tech entrepreneur. 

Wearing a black "Make America Great Again" hat and a T-shirt reading "Occupy Mars," Musk appeared on stage shortly after Trump made his own remarks before a massive crowd of 60,000 supporters. The rally was held at the same site where Trump was shot by gunman Thomas Matthew Crooks on July 13.

"As you can see, I am not just MAGA — I am Dark MAGA," Musk joked, a nod to the Dark Brandon meme. He called the upcoming Nov. 5 election "the most important election of our lifetime."

"This is no ordinary election," Musk claimed. "The other side wants to take away your freedom of speech."
