The US has sanctioned Mexican hip-hop artist El Makabelico for allegedly laundering money for the Cartel del Noreste. Authorities say 50 percent of his streaming royalties go directly to the group, which is accused of drug trafficking, extortion, and human smuggling, BBC reported.

Three senior cartel members—Abdon Rodriguez, Antonio Romero, and Francisco Esqueda—were also sanctioned. The Treasury called the cartel one of Mexico’s most violent and reaffirmed its commitment to cutting off its funding.

El Makabelico’s label, DEL Records, has not commented, according to BBC.
