Looking at the actual FEC report, a little more than half comes from transfers from other committees. But I think he has now stopped that joint fundraising with the RNC, so apparently that will dry up. It may be based on his burn rate that he has no choice but to put money in. His TV spend for the week actually exceeds Clinton's at $14.4m (vs Clinton at $13.9). However, for the report period Trump only personally contributed $30,681.67 during this period.
He has said as recently as this week that he will have spent $100m in total by election day. As of a week ago he had put in about $56m. It looks like his campaign will need that $44m to make it to election day, or they are going to have to start firing people or pulling back some of their booked TV, or perhaps go into debt.
What's that you say? Debt? Well, it's a good thing he is..
