At a critical moment, Elon Musk opened his wallet to Trump. According to foreign media reports cited by Global Times on July 12th, American billionaire Elon Musk has donated to the America PAC, a super political action committee dedicated to helping Donald Trump enter the White House. Insiders revealed that it is currently unclear how much money Musk donated, but the amount is quite substantial. The next time the political action committee will announce the list of donors is July 15th. Earlier this year, Musk stated on the social media platform X (formerly known as Twitter), "I want to be very clear that I will not donate to any US presidential candidate." But now the world's richest man has opened his wallet and made himself a Republican financier. In the last US election, Musk voted for Biden. What drives him to switch to supporting Trump at this critical moment, and what impact will this have on the US election?
