An important vein of presidency scholarship has focused on the president's instruments of unilateral action through systemic considerations of executive orders, proclamations, and most recently, signing statements. This article considers an additional tool: presidential memoranda. I argue these memoranda contain important policy content advancing the president's agenda, and—like executive orders—they often indicate unilateral action. Memoranda use has surged as the issuance of executive orders has decreased, indicating that unilateralism is not declining, but rather, the means of such action may be shifting.
