I just watched that video and they way you characterized it is retarded.
Only so many hours a day and Trump even chuckled after Francis died
Not once in the video you linked does he laugh at the pope dying like you claim here.
and said he will be the next Pope when asked who he approves of being the next Pope.
Yes a light hearted joke to make the reporter feel at ease which he immediately takes back and says he doesn't have a preference on who the new Pope will be.
Try to be more charitable when interpreting the actions of others the portrayal before I watched the video made it seem like Trump was laughing like a mustache twirling villain at the popes death and then declaring himself pope after mocking the popes death.
