Barack Obama, Hillary Clinton and Bernie Sanders weren't too subtle about disguising their feelings at Donald Trump's inauguration.

As Obama, Clinton, and Hillary, entered the US Capitol rotunda in Washington, D.C., for Trump’s historic swearing-in ceremony on Monday, loud boos echoed from the crowd at the Capitol One Arena

WEST PALM BEACH, Fla. -- Former first lady Michelle Obama will skip the inauguration of President-elect Donald Trump, the second time in two weeks that she is not attending a gathering of former U.S. leaders and their spouses, but former Presidents Barack Obama, George W. Bush and Bill Clinton will be there.

Former first lady Michelle Obama won’t attend President-elect Donald Trump’s inauguration, though former President Barack Obama will be there, the Obama’s office said in a statement. No reason was given.

The inauguration is the second gathering of U.S. presidents and their spouses that Michelle Obama has missed in recent weeks.

The planned absence Monday follows another notable absence last week at the state funeral of former president Jimmy Carter.

"A short time from now, we will be changing the name of the Gulf of Mexico to the Gulf of America," Trump said in his speech, prompting Clinton's laughter

WEST PALM BEACH, Fla. — Former first lady Michelle Obama will skip the inauguration of President-elect Donald Trump, the second time in two weeks that she is not attending a gathering of former U.S. leaders and their spouses, but former Presidents Barack Obama, George W. Bush and Bill Clinton will be there.

Michelle Obama was the only spouse absent from the service last week at Washington National Cathedral, where her husband and Trump were seated next to each other and chatted and laughed like old friends despite the history of political animosity between the Democratic former president and the returning Republican.

Barack Obama arrived without Michelle Obama at Donald Trump's inauguration on Monday, 20 January. The 44th president entered the US Capitol's Rotunda solo as he prepared to witness the Republican's swearing-in as the 47th commander-in-chief of the United States.

With Trump experiencing his second inauguration, we decided to look back at the inauguration of the only Black person in America to become U.S. president.
