Travel slush fund comes to mind.
Are Sex Attendants considered a travel cost?
How about the grifters giving an invoice for private jet rate travel (at about 5k/hr or so) to the foundation for reimbursement for “expenses”. Yeah, they made the trip - just on some sucker’s plane at no cost. wink wink.
