On 28 February, OFAC announced that it had sanctioned Jesus Cisneros Hernandez, a Mexican arms trafficker, for having provided, or having attempted to provide, financial, material, or technological support for, or goods or services in support of the Cartel de Jalisco Nueva Generacion (CJNG). CJNG is a violent Mexico-based organisation that traffics a significant proportion of the illicit fentanyl and other deadly drugs that enter the US. The action was taken in coordination with Mexico.
