Traditionally the US President hosts the former President for the unveiling of their official White House portrait., during their first term in office.  Apparently it won't be taking place with the portrait of President Obama, it seems trump is refusing to participate.  In turn, President Obama "has no interest" in participating in the ceremony, as long as trump is in office.  Right now I'm picturing trump's official portrait, someone could be really creative, would love to see a caricature done, but then how could you tell it was a caricature?
