President-elect Donald Trump is being sworn in on Monday as his inauguration ceremony is set to take rare form inside the U.S. Capitol.

As Donald Trump prepares to be sworn in for his second term, a bevy of political leaders, tech CEOs, celebrities and others are in attendance in the U.S. Capitol.

President Joe Biden, Vice President Kamala Harris and all living former presidents attended the funeral, including Bill Clinton, George W. Bush, and Barack Obama. Both President-elect Donald Trump and former Vice President Mike Pence also attended, marking the first time the pair were in the same room in four years.

Former Vice President Mike Pence is in attendance at Trump’s inauguration, his wife, former second lady Karen, is not. Karen Pence snubbed the Trumps earlier this month at Carter’s funeral, where she ignored Melania Trump’s efforts to shake her hand.
