I do not think it was necessary to do that. I think Interim U.S. Attorneys, whose 120-day appointments have expired without the Senate ever voting on their nominations, can be reappointed to an indefinite number of 120-day terms as Interim U.S. Attorneys by the Attorney General under 28 U.S.C. § 546 until and unless the Senate votes down their nominations and so long as they have been nominated for the office in question.
The 120-day term limit does not bar reappointment if done by district court judges. Given that cross-branch appointment of inferior officers is unconstitutional, as I will explain below, there is no reason why 28 U.S.C. § 546 ought to be read as precluding the reappointment of nominated U.S. Attorneys whom Senators do not have the votes to defeat but whose confirmations they are able to delay.
Attorney General Robert Jackson in his famous speech on the role of the federal prosecutor pointed out that from 1789 to the present-day U.S. Attorneys have always required Senate confirmation because of their “immense power” and because they need to win “an expression of confidence in [their] character by both the legislative and the executive branches of the government.” Jackson’s point is certainly true. But a Senate minority that lacks the votes to reject a nominee cannot be rewarded if, after 120 days, they have used Senate procedure to prevent a vote from taking place.
This issue is coming up all over the country right now because Senate Democrats refuse to allow floor votes on President Trump’s nominees to be U.S. Attorney. The matter is thus of great practical importance in the District of New Jersey and in other Districts as well.
