Dear President Biden:

We write as organizations with a steadfast commitment to justice for grave international crimes and therefore to the success of the International Criminal Court (ICC). We urge your administration to oppose the threats and calls for punitive actions against the Court that several U.S. lawmakers have recently made. Acting on these calls would do grave harm to the interests of all victims globally and to the U.S. government’s ability to champion human rights and the cause of justice, which are stated priorities of your administration.

Accountability is important for its own sake and protects against the commission of future atrocity crimes. Acting where it has jurisdiction and within its mandate as a court of last resort, the ICC works together with national authorities to ensure perpetrators of such crimes are held to account and that victims and affected communities find some measure of justice. While the United States is not an ICC member country, Republican and Democratic administrations have supported the Court in specific cases, and the U.S. has assisted arrest operations to bring justice to victims in central Africa. Your own administration has recognized the Court’s essential role to address serious crimes in Ukraine and Darfur.

We are alarmed by threats that U.S. lawmakers have aimed at the Court in recent weeks including the letter sent on April 24 by Senators, threatening to sanction the ICC prosecutor’s “employees and associates,” if steps were taken to pursue arrest warrants against Israeli officials. On May 20, the ICC prosecutor requested warrants for leaders of Hamas and Israeli officials stemming from his ongoing Palestine investigation; ICC judges will assess the request to determine whether to issue warrants.
