Most of us expected something like this to happen, but there's an interesting detail here I never expected.
As far as I know, voided pardons are not a thing. Meaning a president can pardon anyone before he leaves office (I don't necessarily support these king like powers, but) and the next administration can do absolutely nothing about it.
But since some of the pardons were questionable, to put it nicely, I thought we would see "new charges" being drawn up to go after some of the people on the special lists. (Fauci comes to mind, for example)
At any rate, I never expected to learn that Biden's mind was so far gone, that he had stopped signing papers altogether. In other words, they pulled a Reagan on us once again.
These are some crazy times. We will see what happens next. But honestly, it all could be theater too.
