What is clear about the pardon power’s end point, however, is the delineation between federal and state investigations, charges and prosecutions. A president has absolutely unlimited power to dispense with the former while the pardon clearly does not extend to the latter.

But in a somewhat curious turn, Weissmann called on the acting U.S. Attorney for Southern District of New York (SDNY) to make headlines for herself by bringing Stone in for questioning before an as-yet not constituted–or at least as-yet not public–grand jury.

“Audrey Strauss: this is your moment to stand for the rule of law,” Weissmann tweeted.

But it’s unclear exactly why and for what reasons Stone would be of interest to the SDNY at the moment. There’s also the salient issue that the SDNY’s jurisdiction is federal–they are part of the U.S. Department of Justice–so any resulting charges, unless serially dragged out, would likely be extinguished by Trump yet again.
