It would be funny (an appropriate) if Pence issued a statement that read something to the effect of:
"Given that I work for/with President Donald Trump, it would not be appropriate for me to attend any funeral(s) or other events meant to Honor any persons who have been involved with Anti-American Interests.
Knowing this in advance may ease some complications for those involved in making such arrangements. I, like President Trump, only have the interests of The American People at heart and will act accordingly in any such circumstance that may present itself, now or in the future."
