On July 9, local time, U.S. Treasury Secretary Scott Bessant once again mocked Musk's move to establish the "American Party" at the "Billionaire Summer Camp" event held in Sun Valley, Idaho. Bessant laughed and said: "He may be able to win votes on Mars." This is not the first time that Bessant has mocked Musk for "setting up a new camp." In an interview on the 6th, he said that Musk's announcement of the establishment of the "American Party" said that the directors of Tesla and Space Exploration Technologies, which Musk is in charge of, "do not like" this move, and they "will encourage him to focus on business rather than political activities." Bessant said, "If you look at the polls, Elon is not popular." Musk also responded to Bessant on social media on the 6th, saying that the U.S. Treasury Secretary "majored in political science and doesn't even understand mathematics."
