John Phelan has resigned from his role as Secretary of the Navy, with the Pentagon announcing his departure on Wednesday. The reasons for his resignation remain unclear, although sources suggest he may have been fired. Phelan had addressed a large audience just a day prior at a Navy conference in Washington, discussing his agenda. His resignation follows recent firings by Defense Secretary Pete Hegseth, including Army General Randy George. Hung Cao, who has been appointed as the interim Secretary of the Navy, is a veteran who fled Vietnam in 1975 and has extensive military experience, including service in Special Operations. He holds a Master's degree in physics and has worked on the Navy's budget and collaborated with the FBI's Joint Terrorism Task Force. In contrast, Phelan lacked military experience and had previously been a significant donor to former President Donald Trump's campaign.
