This footage tweeted by ICC shows US Attorney General Merrick Garland visiting ICC Headquarters in The Hague, Netherlands on Mon 19 Jun 2023.
It shows Mr Garland meeting ICC President Judge Piotr Hofmanski, ICC Chief Prosecutor Karim Khan KC and ICC Registrar Osvaldo Zavala Giler.
The end of the clip shows Mr Garland sitting at a table signing a document.
Maybe the US is signing up to the ICC or just wants to be seen as supporting it by sharing intel evidence to help catch people accused of war crimes etc.

Note, in 2020, the largest contributions came from Japan, Germany, France, and the United Kingdom. Some countries, notably Brazil and Venezuela, have run up millions of dollars in overdue payments.
Washington has backed ICC efforts on several occasions, however. In 2005, the Bush administration allowed the Security Council to refer the Darfur case, and it later offered to assist the court’s investigation, which legal experts saw as a softening of the US stance. In 2011, the Barack Obama administration voted in favour of the Security Council referral for a Libya investigation. It also helped deliver several fugitives to The Hague and offered to pay millions of dollars as rewards for information on individuals accused of atrocities.
