Trump has made it clear that Musk cannot become president of the United States, emphasizing this point on multiple occasions. The main reason is that according to the U.S. Constitution, the president must be a citizen born in the United States, and Musk was born in South Africa, thus he is not legally qualified to hold the position of U.S. president.
Furthermore, although there is a certain level of collaboration between Musk and Trump, such as Musk being appointed to lead a department aimed at improving government efficiency, cutting costs, and deregulating, Trump insists that this does not mean Musk will replace him or gain the presidency. Trump also mentioned that rumors about him 'giving' the presidential position to Musk are false, and his high regard for Musk does not change this fact.
Although Musk is not a U.S. born citizen and cannot become president, his influence on America is indeed very significant, especially in terms of expressing opinions through his social media platform X (formerly Twitter) and influencing policy. At the same time, Musk is also one of the largest individual donors in the 2024 U.S. presidential election, which has a considerable impact on the election.
