Funny and clever Broadway-style song (with photo-shop interview bits) showcasing Trump's ridiculous public communicators' lies.
Context for anyone not keeping up with US news: the (non-existent) Obama 6 month Iraqi ban mentioned by Trump's people in the clip didn't happen, though in 2011 they did reexamine Iraqi immigrants, and significantly slowed down Iraqi refugee inflow while doing so. This occurred because 2 Iraqis were arrested in 2011 in Bowling Green, Kentucky, US for plotting to send weapons and money to Al Qaeda.
There was no Bowling Green violence, no massacre, though I have a distant recollection of hearing a (radio) sports story a couple years ago about Bowling Green (Ohio, US) college rugby team which slaughtered its rivals 100+ to 0 in a rugby game in the 1920s, termed "The Bowling Green Massacre". (Can't find that on Google but I'm sure I remember hearing about it.)
