Clinton was caught on camera snickering as Trump vowed to change "the name of the Gulf of Mexico to the Gulf of America."

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

As Barack, 63, Bill, 78, and Hillary, 77, entered the U.S. Capitol rotunda in Washington, D.C., on Monday for the 78-year-old’s historic swearing-in ceremony, people at the Capitol One Arena could be heard loudly booing.

The guest list includes some of America’s most influential tech billionaires and politicians as well as some foreign leaders and celebrities who have embraced Trump.

Just ten days ago, at Jimmy Carter's state funeral at Washington National Cathedral today, all five living U.S. presidents attended: Bill Clinton, George W. Bush, Barack Obama, Donald Trump, and Joe Biden. Today, all five men were once again in the same place, as Clinton, Bush, Obama, and Biden attended Trump's inauguration.
