Remember, the ICC is primarily a court of last resort, responsible for prosecuting individuals for international crimes such as genocide when national courts are unable or unwilling to do so. It operates under the framework of international law, and thus any intervention on its actions by individual countries would have to be handled very delicily in order not to undermine its independence.
Any direct intervention from Biden would likely involve diplomatic talks or negotiations, either with the ICC itself or with other countries connected to the situation. However, it’s important to know that these details are speculative in nature and based on how international processes usually work.
