The vast majority of it is.
No Super PACS like Ted, and all donations dont cover the amount he’s spent, which isn’t very much.
The inside story of Trump campaign’s connections to a big-money super PAC

What Trump doesn’t say is that he and his top campaign aide have connections to a super PAC collecting large checks to support his candidacy — a group viewed by people familiar with his campaign as the sanctioned outlet for wealthy donors.
This summer, Trump appeared at at least two events for the Make America Great Again PAC, which took his campaign slogan as its name and received financing from his daughter’s mother-in-law. A consultant for the super PAC is a Republican operative who has previously worked with Trump’s campaign manager, Corey Lewandowski, according to several people with direct knowledge of their ties.
