Why hasn't Robert Mueller subpoenaed Trump? Three theories about the Russia investigation
There are several reasons why Mueller may decide to forgo a presidential grand jury subpoena altogether.

One might ask, why doesnt Mueller just subpoena the president to force him to tell the grand jury his side of the story on a variety of topics, including why he fired former FBI Director James Comey and why he participated in drafting an inaccurate narrative about the Trump Tower meeting between members of his campaign and Russian representatives. My 30 years of experience as a federal prosecutor tell me that there are at least three possible reasons why Mueller may decide to forgo a presidential grand jury subpoena altogether.
First, Mueller may have gathered so much evidence that he can reach informed conclusions about how to proceed without securing the presidents testimony. Given that prosecutors invariably take a more is more approach to developing evidence,
I think this possibility is less than likely.
Second, given that the presidents lawyers have argued (incorrectly, in my opinion) that a sitting president cannot be subpoenaed to the grand jury, it may be that Mueller wants to avoid the protracted litigation that would erupt concerning the legality/enforceability of such a subpoena. Although this is a distinct possibility, I strongly suspect that Mueller is prepared to take as much time as needed to conduct a full investigation.
Accordingly, the delay occasioned by having to fight a legal battle over a presidential grand jury subpoena is probably not driving his decisions.
The third possibility and one that I suggest is growing more likely by the day is that
evidentiary developments in the investigation may have moved the president from being a subject of the investigation to being a target. If this is the case, then Department of Justice policies would strongly argue against using a grand jury subpoena to compel the president to testify.
