To put the point in mildest terms, Ellen Weintraub and Don McGahn do not get along. When they served together on the Federal Election Commission, their mutual hostility was well enough known, and their time apart since Mr. McGahn left the agency does not appear to have eased the tension – – certainly not on Commissioner Weintraub's side, and probably not on Mr. McGahn's. Now Ms. Weintraub has published an op-ed in The Washington Post, arguing on the basis of her experience with Don McGahn that he is not fit to be the next White House Counsel.

How McGahn will perform in his current job might be judged as Commissioner Weintraub suggests, by putting the weight she does on a particular reading of his record at the FEC. Or, on a different view, a distinction could be drawn between Mr. McGahn's past and future roles, and a different standard of evaluation could be adopted for the work now ahead of him. In choosing the first of these alternatives, the Commissioner may be incorrectly framing the question of McGahn's suitability as White House Counsel and directing attention away from what is more relevant in assessing the role and performance of that Counsel in the incoming Administration.

Mark Patterson observes that Donald Trump refuses to make the personal tax disclosure that is routinely and without exception expected of senior federal officials. He describes Congress’ strict enforcement of this obligation, which includes the deep probing of returns by the Senate Finance and other congressional committees that, in Patterson’s words, require “answers [to] dozens of detailed questions about sources of income, deductions, investments, tax treatment (and immigration status] of domestic employees and other topics.” Yet Trump says that in his case, it is “none of your business,” and so he is relying on the absence of any legal requirement of disclosure to deny the public what the senior officials he would appoint if President would have to provide. Patterson recommends that either the law be amended to compel presidential candidates to release this information or to provide it to congressional committees for review followed by a public assessment. (Note: Mark is one my colleagues at Perkins Coie.)

Why would presidential candidates, charged with reporting specific categories of financial information, not have to include their tax returns? The choice now is deemed to be theirs: a choice determined only by the pressures, or incentives or disincentives, of the political “marketplace”, or a personal sense of ethical obligation.

Committing this question to a purely political resolution represents a judgment that voters will set and enforce the transparency standard. They will either reward disclosure or punish candidates for resisting it, but one way or the other, voter will is what counts, and there is no need or place for a legal requirement. In fact, on this theory, it is better for the question to be referred to the voters, because they are the ones to ‘vet” the presidential candidate and to insist on what information they should have to meet their “vetting” function.
