btw, it doesnt have to be a dead relative.
Make up a nom de plume.
Not that you would get busted, but I would bet they have some law that would make any concealment of a payment or transfer of funds illegal. And trying to do it with Trump might just increase your exposure these days. Don’t forget, as far as we know they haven’t pulled his FISA, so he is still under full surveillance off a hop from Carter Page, and they get another hop to put you under full surveillance if you ever deal with him.
Plus, without going into too much detail of my own circumstances, I can tell you that you should never do anything these days under the assumption you are not being watched, no matter how minor you are. If you are here, things may not work the way you think, for you.
