The White House issued on 4 May 2023 an "Executive Order Imposing Sanctions on Certain Persons Destabilizing Sudan and Undermining the Goal of a Democratic Transition."
President Biden in an executive order detailed reasons for imposing sanctions on foreign persons determined by the Secretary of the Treasury, in consultation with the Secretary of State, for actions or policies that threaten the peace, security, or stability of Sudan. The executive order does not identify any individual by name but offers a wide range of reasons for potentially sanctioning offending individuals.
The Hill published on 5 May 2023 an article titled "Biden Expands Ability to Sanction In Response to Violence in Sudan" by Brett Samuels.
The article offers some background on President Biden's executive order.
