I found this article from Lawfare, back in 2017, when Don McGahn was mangling the job of WH Legal Counsel. Obama’s WH Counsel wrote this article. Here is his take on the enumerated job duties:
But there are a few guidelines, working principles, which have emerged from this tumultuous experience and help clarify the proper role of the White House Counsel.
First is the one already noted: the counsel in any situation must be clear about the “client” interest she is serving when giving advice. It may often be that good advice serves all the relevant interests—the particular president’s, the Office’s, and the public’s. But this can be a more complex and demanding judgment than it seems.
Second, the White House Counsel is the lawyer and not the client, an agent and not a principal. It is one of the reasons that White House Counsels do well, as a general matter, to refrain from weighing in on the substance of policy questions. It is usually a mistake for the Counsel to attempt to be both lawyer and a constituent member of the “client,” because if engaged in policy, the lawyer may be inclined toward a legal position helpful to her policy preference, and others in the policy debate may suspect bias (even if there is none) and lose confidence in the Counsel’s professional objectivity.
Third, the lawyer has special responsibility for legal and ethics compliance within the West Wing. She may have to advise on a wide range of areas, increasingly including national security, but a bedrock responsibility is ensuring the adherence to law and ethics standards by the President and the staff.
Fourth, the White House Counsel has to be an honest broker in matters of process in which she is involved. The resolution of legal issues that concern the president may be the primary responsibility, or require the participation, of the legal staffs of other Departments or agencies. The Counsel has a role in assuring that whenever she will be the one fashioning and delivering the advice, all informed views of affected agencies considered. There are other instances in which she is not the appropriate legal decision-maker or adviser, but coordinates the development and delivery of the advice.
Finally, the Counsel must determine how all of these responsibilities are most effectively performed in the particular presidency, taking into consideration the specific tone set, the policies emphasized, and the political challenges faced by the occupant of the office. This is not to suggest that the White House Counsel is just the president’s lawyer and must keep closely attuned to what that president wants. It means that the lawyer cannot represent all the relevant interests without a thoroughgoing appreciation of the political and policy environment within which she is working.
ETA: I bolded the Third section. That is the one I think is most important…
I think Cipollone’s testimony to the J6 Committee is going to turn out to be a nothingburger. Especially given that he seems to “not remember” saying one of the most important things attributed to him by others. Convenient – but fully cooperating.
