I watched that TV show segment again. The trumpet reference is to a very rich, very annoying political idiot called Clive Palmer who has decided to reinvent his very annoying political party and he has named it Trumpet of Patriots, and his slogan is Make Australia Great Again.

He is also trying to convince another very annoying politician, Pauline Hanson, from another very annoying political party to join forces with him. That is just sad because the reasoning behind joining forces with each other is that neither party has had very much success over the years in getting many candidates elected. BooHoo!! :-(

One of the cartoons is by Warren Brown and it shows Trump on the left, then Palmer blowing a trumpet, and then the word trumpette to indicate Clive Palmer farting.

The other cartoon by Stilgherian looks like a straight copy of an old Mediaeval image: a man with a very long trumpet coming out of his backside and a flag - I'm not sure what it is supposed to represent - hanging from the trumpet.
