My understanding is that there is some bad spirits or bad ghosts occupying white house. So white house is a haunted building. That is the reason Kennedy was killed. Bill clinton had sex scandal in white house. Finally came Obama who has mental problems. Bad Ghosts are extremely dangerous. If they takeover some building or some person then serious problem for many decades. This is the reason, ultimate decisions taken by USA presidents from white house have resulted in $75 Trillion debts for USA. People say there are Ghosts in Buckingham palace.
