The Executive Order on Combating Anti-Semitism, officially Executive Order 13899, is an executive order announced on December 10, 2019, and signed the next day by U.S. President Donald Trump. The said purpose of the order was to prevent antisemitism by making it easier to use laws which prohibit institutional discrimination against people based on race, color or national origin to punish discrimination against Jewish people, including opposition to Israel uniquely as a Jewish nation-state without opposition to other nation-states. The definition of antisemitism used in the executive order was written by the Holocaust Remembrance Alliance and has been criticised as conflating it with criticism of Zionism or the state of Israel.
