The Treasury Department, trying to block an elaborate money-laundering scheme, has announced that two Mexican cattle companies are fronts for drug-trafficking cartels.

The action means that cattle sold by the companies to Texas ranchers after Friday's announcement are subject to seizure by the federal government, said a high-ranking Treasury official who asked not to be named.

"Cattle already purchased and owned before the companies were identified as tied to the drug cartels are not going to suddenly be blocked," the official said.

For the life of me I can't see why a "high-ranking Treasury official" would request anonymity in this case. Has it reached the point that American officials fear retaliation from Mexican drug lords—or Texas ranchers?

Two Mexican drug cartels were named in the Treasury Department's statement, the Arriola Marquez organization and the Arellano Felix cartel based in Tijuana. The Arriola Marquez group, based in Mexico's Chihuahua state, is linked to Mexican drug kingpin Joaquin "El Chapo" Guzman, the department said. Guzman leads one of the factions fighting for control of Nuevo Laredo and its smuggling routes into Texas, officials have said.
