International Holocaust Remembrance Day is the United Nations–designated day to commemorate victims of the Holocaust; it is observed on January 27 because that is the anniversary of the liberation of the Auschwitz‑Birkenau camp by Soviet forces on January 27, 1945 (UN General Assembly resolution 60/7, 2005, formally established the day).
Auschwitz‑Birkenau was the largest Nazi concentration and extermination complex in German‑occupied Poland where roughly 1.1 million people were deported and murdered (about 1 million of them Jewish); it included gas chambers/crematoria, forced labor, starvation, and medical experiments—its liberation on January 27, 1945 revealed the industrial scale of the Nazi genocide and made the site emblematic of the Holocaust.
Federal "legal tools" include criminal prosecution under federal hate‑crime statutes (e.g., the Matthew Shepard and James Byrd, Jr. Hate Crimes Prevention Act, 18 U.S.C. §249), civil‑rights enforcement (for example Title VI enforcement in education settings), FBI investigations and prosecutions by the Department of Justice, civil remedies and injunctions, and provision of grants/technical assistance to state and local authorities. Agencies also issue guidance and use executive actions to direct enforcement priorities.
Measures are typically implemented or enforced by the Department of Justice (Civil Rights Division and U.S. Attorney offices) and the FBI (investigation/prosecution), the Department of Education’s Office for Civil Rights (enforcement of Title VI in schools and universities), and other agencies that support security and threat‑response (e.g., DHS components and CISA for protective guidance).
In this White House message the phrase "the 47th President of the United States" refers to the President identified on the White House website where the statement appears—President Donald J. Trump. (The message is posted on the White House site listing President Donald J. Trump in the Administration menu.)
The U.S. government has not enacted a single statutory definition of "anti‑Semitism;" instead federal agencies use operational definitions in policy guidance. For enforcement purposes the Department of Education (OCR) treats antisemitism as discrimination based on shared ancestry/ethnic characteristics under Title VI and (in guidance and in implementing Executive Order 13899) instructs officials to consider widely used working definitions such as the International Holocaust Remembrance Alliance (IHRA) working definition when assessing incidents.
