In July 2020, the AHA endorsed a Senate resolution introduced by Sen. Elizabeth Warren recognizing the forthcoming centennial of the Tulsa Race Massacre of 1921. Senator Warren and Congresswoman Sheila Jackson Lee reintroduced this bill on March 10, 2021, and the AHA once again endorsed it. “Everything has a history, including white supremacy and the many forms of violence, coercion, and cultural practices that have legitimated and enforced it,” said AHA executive director Jim Grossman. “What happened in Tulsa was extreme, but not unusual. It is part of our nation's heritage. We must acknowledge that heritage, learn from it, and do whatever each of us can to ensure that it is just that—heritage, rather than continuing practice.”
