Marc Short, director of legislative affairs at the White House, will leave his position by July 20 to consult for Guidepost Strategies and teach at the University of Virginia's Darden School of Business, where he will also serve as a senior fellow for the non-partisan Miller Center, reports Politico.

Why it matters: In addition to being a frequent cable news surrogate for the president, Short is one of the administration's longest-serving senior aides and worked closely on several high profile policy initiatives, including the efforts to repeal the Affordable Care Act and overhaul the tax code.
