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

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.

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.

A video showing Donald Trump and Barack Obama, two political rivals, engaging in a casual conversation at the state funeral of Jimmy Carter went viral last week.

Former Presidents Barack Obama, George W. Bush and Bill Clinton have said they would attend, along with former first ladies Laura Bush and Hillary Clinton, who was also Secretary of State.

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

Rather than wear MAGA red or bipartisan white, they dressed in the color of democracy. Bill, the 42nd U.S. president, was sharp in a dark navy suit, white shirt, and bright blue tie. Hillary coordinated in her own power suit, composed of a buttoned-up coat and tailored pants, in a deep royal blue. Her coat was adorned with a gold-and-blue pin.

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.

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