No. It's because of the Epstein files.
Did she actually do the bare minimum of what she was legally required to do? No. Those lawsuits are pending because it's so fucking obvious she didn't release stuff (Congresscritters who had access to much of it came out and said so).
Did she intentionally try to hide Trump and his cronies presence in the Epstein files? Yes.
If she took all these steps, and put herself in legal jeopardy, just to protect Trump and his cronies, why is he still mad at her?
It's because she released them at all. I'm sure he was expecting her to delay the release forever. Or at least until all the lawsuits played out (which could complete after his term).
The underlying truth here is actually just the usual Trump stuff: He doesn't surround himself with competent people. He only chooses people based on perceived loyalty and whims.
