Trump has a lot of contacts in the world of charity because he rents out ballrooms, hotel ballrooms, the ballroom at Mar-a-Lago to charities. Charities are often the ones that rent out these ballrooms for big events.

We Harvard students live in a tourist attraction with movie stars and geniuses; we're recognized on all continents as the creme of the brulee, the syrup on the pancakes of greatness. Yet most of us complain like vegans at a barbecue cook-off.

If I'm owed money, but I say, 'Don't pay me, pay my cousin. Don't pay me, pay my charity,' you can do that, but then the IRS requires that you pay income tax on that. It's your income if you earned it and you directed where it went. If you exercised control over where the money went, you have to pay income tax on that.

Nonprofits such as the Trump Foundation are prohibited from giving political gifts.

If you're the president of a charity, you can't take the money out of the charity and use it to buy things for yourself. And you can't take the money out of the charity and use it to buy things for your business.
