This beast of a fly was on his head for at least 2 full minutes. Seriously...no one was able to make a subtle mention to him?

I thought the same thing.  For a moment, I thought the thing died and was gonna be there all night.  

Maybe he fly laid eggs and Pence will have a head full of maggots soon. Cheers!

I was just thinking that Trump dosn't have to worry about a fly landing on his head because his flap of comb over hair would act as a fly swatter. I am also working on a new song about Donald Trump and it will be sung to the tune of one of Caray Simon's songs. Here is what I got so far - you're so vain I bet you think that fly on Mike's head is about you - don't you don't you. Cheers!

Maybe the fly noticed that Pence's fly was undone and wanted to distract attention away.

If Pence didn't feel that fly, then my theory that he's been stuffed by a taxidermist might be accurate.

Undead, so unable to feel it. His daughter is a vampire (no reflection) ...

hahaha
that was hilarious 
you know of course what flies
are attracted too, right?

If was more exciting watching the fly than listening to Pence talk.
