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.

Michelle Obama skipped the ceremony but former Presidents Joe Biden, Barack Obama, George W. Bush, and Bill Clinton attended Trump's inauguration.
