Donald Trump brought to light a "President Walk of Fame" featuring the portraits of every president of the US expect that of Joe Biden.

This move withstands with the long feud between the Democrats and Republicans. Is this the history of Presidential elections or Trump was just making fun of the walls of the West Wing?
