Legacy-wise, this a guy posing for selfies with his own executioner on the steps to the gallows.
A footnote from the WSJ:
The Obamas canceled a photo-op of the current and future first couples outside the south entrance of the White House. In his first visit to the White House after the 2008 election, Mr. Obama and first lady Michelle Obama posed for the cameras alongside President George W. Bush and first lady Laura Bush. The decision not to participate in this tradition illustrates how bitter the campaign was, particularly for Mrs. Obama who delivered some of the most emotional arguments against electing Mr. Trump.
I thought they might cancel this joint appearance too, but no, decorum demands the public handshake. In an alternate universe this press conference ends with Trump announcing that he only ran for president in order to land this face-to-face meeting with Obama, so that he could finally ask him directly, “Where’s the birth certificate?”
May you live in interesting times.
