Methinks this is BS. Trump’s camp is never going to truly leak any potential weakness or state that they are low on cash ever.
Manafort has said things that have been construed wrong before like about how Trump was going to change going into the general. Trump obviously hasn’t.
DJT has been doing this his entire life. It’s called getting and using OPM - other people’s money. Why should he use his own when he can cajole through various means all the old farts at the RNC to give him some walking around money. He will eventually have a number of sources of capital. His campaign will not fail for lack of cash - other things maybe, but he knows how to get financing.
