President-elect Trump’s inauguration is drawing the CEOs of some big-name companies. 

The nation’s 47th president is slated to be officially sworn in on Monday, with his oath of office taking place within the U.S. Capitol building. 

Late last week, it was announced that Monday’s inauguration would move indoors due to cold temperatures and the potential windchill factor.

Photographers captured billionaire Amazon founder Jeff Bezos as he showed up for the ceremony. He was joined by fiancee Lauren Sanchez. 

Tesla CEO Elon Musk, a major supporter of Trump and one of the heads of the president-elect’s Department of Government Efficiency (DOGE), was also in attendance. 

Inside the Capitol, OpenAI CEO Sam Altman took some time to engage in conversation with influencers and boxers Jake and Logan Paul.

TikTok CEO Shou Zi Chew was also in attendance on Monday. The company's app stopped working for U.S. users late on Saturday before a law shutting it down on national security grounds took effect on Sunday. However, it began restoring its services on Sunday after Trump said he would revive the app's access in the U.S. when he returns to power on Monday.
