There's a reason Trump can't raise money for his PAC. No one wants to pay for his legal bills.
Now he has moved the problem into the RNC, I expect the Dems will widely advertise the fact that much of the money pays Trump's lawyers. So that the RNC spigot is also switched off.
No wonder many Republicans in the Senate and House who depend upon the RNC are extremely angry about Trump's takeover. This is an obvious target for the Dems. And is yet one more way that Don the Con avoids paying his own bills.
