I wonder if Mike Johnson is in that same situation, all it took for him to go full Ukraine funding was 1-2 intelligence briefings, I think the intelligence was something to make it easy for him to change his mind about his personal life.
Politics is not for the honest. Maybe initially, the Mr smith goes to washington kind of thing, and it is nice to get one evey now and then, but the constant temptation is likely very strong, and ultimately, most with normal character do have a price. Only the amount varies.
The price may be a few million, or a bevy of irrisitable babes (or males for those types), or perhaps NOT killing your first born, and pets, and burning down your house.
Realize, those several billion that go missing regularly, and the several hundreds of billions that get washed domestically and via foreign aid do end up somewhere, ind it is not into the pockets of honest people.
Lot of money and power at stake, so "drinking the potomac water" is likely easier then self immolation.
