Though Trump still DID exert pressure to conduct investigations according to the CNN article I linked, right?

Exert pressure? He asked his Chief of Staff, and his Chief of Staff said that you couldn't do that. From the article, Kelly apparently told him that "It’s inappropriate, it’s illegal, it’s against their integrity and the I.R.S. knows what it’s doing and it’s not a good idea...." I fully expect that Susie Wiles would tell him the same thing, if he asked again. From context, it stopped right there with Kelly last time - and again, I expect the same thing would happen with Wiles.

Not because I have any belief that she sees her job as stopping Trump from doing what he wants to do, BTW. But she will tell him when something's completely illegal, and she is unlikely to do anything completely illegal herself.
Because you can't do this kind of stuff without creating a discoverable trail - and even though Trump might be free from any fear or criminal consequences, everyone else in that trail would risk going to jail for that kind of thing. Trump is never going to be in a room, alone, with the sort of very junior people who would need to actually implement this type of scheme. It can't happen. At a minimum, he'd have to tell Wiles to tell Bessent to tell the IRS Commissioner to tell a senior person in tax compliance to get the junior people do it - and that's just too many people. Susie Wiles doesn't have a get out of jail free card from SCOTUS, and neither does anyone in Treasury.
