Is There Any Revoking Or Reversing a Presidential Pardon?

Morning, Glories. Cold one, too.

So, I was thinking about Holder, Jarrett, and all the other unindicted co-conspirators, and the justice that should (but, alas, probably won't) be brought down upon their heads, and I got to wondering...

Is there any revoking or reversing a Presidential pardon? Because, I expect wholesale absolution of the whole gang of traitors is already being readied for the SCOAMF's pen.

How did we get in this mess?
