On July 16, CNN reported that last year, former US President Trump posted a 'major and exciting announcement' on the 'Truth Social' platform. At that time, Nvidia had just announced plans to build an artificial intelligence supercomputer in the United States. On April 15, 2025, Trump promised his over 9 million followers that he would expedite the processing and swiftly deliver all necessary permits for Nvidia and similar companies. However, what Trump did not disclose was that he had just purchased Nvidia stocks worth between $200,000 and $500,000 a few days earlier. CNN's investigation found that days after Trump bought stocks in more than 20 companies, he promoted these companies on his social media accounts and sometimes announced government actions that could benefit the companies he had just invested in. The White House strongly denied that Trump used his position for personal gain, stating that all his actions were aimed at benefiting the American public and that all of the president's stock transactions were managed by external financial managers, with Trump and his family having no control over specific transactions.
