That money is just to employ lobbyists and their associated expenses.
I'm sure there is additional money for lobbying that is not on the books. Holidays, houses, good bullion, crypto, free memberships to exclusive clubs and the like that is gifted to politician's and their spouses by big industry.
So with regards to FTX these were listed in the same spreadsheet as "Gifts", and there were some, but we're still talking low five figures for the majority of politicians. And it's not like FTX were not willing to spend more, they spent $68M on Tom Brady and Giselle for a two year contract to advertise FTX, or $500k on hotel rooms for interns in Miami.
It's getting far more regulated though, and that's a good thing - big Pharma pushing drugs to doctors is one of the most sickening parts of capitalism.
