 During the 2016 U.S. presidential campaign, Epshteyn acted as a senior advisor to the Donald Trump campaign, making frequent television appearances as a Trump media surrogate on Trump's behalf.In September 2016, Epshteyn responded to a question from MSNBC's Hallie Jackson by offering a new explanation for why a portrait of Trump – paid for by the Donald J. Trump Foundation – wound up on display at Trump National Doral Miami, a Trump-owned for-profit golf resort in Florida.Epshteyn said, "There are IRS rules which specifically state that when a foundation has an item, an individual can store those items – on behalf of the foundation – in order to help it with storage costs... And that's absolutely proper."
