Pardoning Maxwell would be an insanely bad idea. The MAGA world love two things more than anything else; conspiracy theories, and imagining themselves in an endless war against a cabal of powerful pedophiles.
Maxwell directly aided and abetted one of those powerful pedophiles. To MAGA, there is no possible justification for pardoning her. It would be tantamount to a full admission from Trump, and it would send their conspiracy addled minds into overdrive. At best (for him), they'd wonder what kind of leverage she has over Trump in order to buy herself a pardon. If not evidence of pedophilia, then surely something else, right?
Is Maxwell angling for a pardon? Almost certainly. But giving her one would be a suicidal move for the administration right now.
