Elon Musk speaks at Trump rally, says the 45th president must win to 'preserve the constitution'

Tesla CEO and X owner Elon Musk took the stage at former President Donald Trump's rally in Butler, Pennsylvania, where he urged people to vote. 

"President Trump must win to preserve the Constitution," Musk said on Saturday. "He must win to preserve democracy in America."

When Trump introduced Musk on stage, he said that he "saved free speech" by purchasing the social media platform, X, and making it a platform for free speech. 

"This one request," Musk said. "It's very important. Register to vote, and get everyone you know and everyone you don't know — drag them to register to vote."

Musk said that if people don't vote in this election, he predicted it would be the last election. 

"This election could be decided by 1,000 votes, 500 votes [or] a tiny margin," Musk said. "So get everyone you know to register to vote."

Musk concluded his remarks by saying, "Vote! Vote! Vote! Fight! Fight! Fight!"
