The first presidential portrait was an oil paiting of George Washington done by Gilbet Staurt. Since then, it has been tradition for every president to have a portrait taken during their time in office. The tradition continues today, although due to technology advances, the portrait may be a photograph instead of an oil painting. The portraits end up in the National Portrait Gallery but elected presidents may loan the portraits to hang in the oval office during their term. The gallery has collected portraits since 1962 and began commissioning their portraits starting with George Bush in 1994. During Donald Trumps presidency, in 2018, he signed Public Law 115-158, which prohibits the use of federal funds to pay for an official portrait of any federal official or officer, including the president, the vice president, a member of Congress, the head of an executive agency, or the head of an office of the legislative branch. Most recent presidential portraits have been privately funded anyways, but this law will prevent other governmentt officials commissioning official portraits using federal funds.
