A major reason that Trump can get away with so much is that Congress is supine. There's quite a lot they could and should be doing to rein in a rogue president but they simply choose not to. Even in matters that are delegated to them directly like raising and spending money.
Checks and balances only work when your mechanisms actually do their constitutionally mandated role.
You have to start to ask why these people have sold out their country to Trump.
I think they were all chosen because they are corrupt, and Trump, or someone else further up the food chain knows it, and has the tapes, and once the job is done, the US ruined, and no longer a world power, they will be left to hold the smoking gun.
I do believe that when Trump falls, so will Maga, and much of the republican party, and the next president, if untainted not caught in the same web, will have to gut every department of government to cleanse it.
In the future everyone will ask, how did you not see your country being taken over?
