I am sorry, I can’t give you a name, but recommend you go to Trump’s website, where they have a phone number for his campaign and I am sure they would be able to get you in touch with the right person(s).

Be prepared to call many times before you actually get past the “all circuits are busy right now” -— but persistence pays off.
I have spoken to the campaign a dozen times about several matters. An intern takes a message and say they will pass it on. No response has ever come back.
