Donald Trump's inauguration will feature high-profile performers, influential business leaders, and foreign dignitaries, marking a significant departure from previous traditions. While initially planned for an outdoor ceremony, the event has been moved indoors due to freezing temperatures. Musical acts like Carrie Underwood and the Village People will perform, and global leaders, including Argentina's President Javier Milei, will attend. Trump’s address will focus on unity, fairness, and key policy promises, setting the tone for his second term.
