Now, however, New York Magazine has reported what Mr Bush really thought of the ceremony and the incoming president's address.

"That was some weird s---," Mr Bush said, according the magazine, which cited three people present.

A spokesman for Bush declined to comment, the magazine said.

During the inauguration, Mr Bush sat near Bill and Hillary Clinton as well as Barack and Michelle Obama.

Ahead of the event, Mr Bush's office said the couple was “pleased to be able to witness the peaceful transfer of power - a hallmark of American democracy - and swearing-in of President Trump and Vice President Pence.”

Although he did not support Mr Trump during last year's presidential campaign, Mr Bush congratulated Mr Trump after his victory.
