To be honest, I am not happy about Trump's financial trouble. To maintain his wealth, he will sell his soul to the highest bidder, whether it is Putin, Musk, or some other powerful individual or entity who would like serve their own interests. Anyone who thinks Biden and the Democrats are the ones putting him in this position is naive. It is not good for them or for the country.

RNC does not HAVE to pay it. They may choose to pay or not.  
Personally, I do not care, it is not my money in any case.  I do not give money to any politician or political committee.
