To further assist Mexico, the White House on April 15 named a former U.S. Justice Department official to lead efforts to crack down on drug-related violence along the U.S. side of its southwest border with Mexico.  Homeland Security Secretary Janet Napolitano announced the appointment of Alan Bersin, a former federal prosecutor, during a visit to El Paso, Texas.  Bersin held the same post - dubbed "border czar" - during the Clinton administration. And three Mexican drug gangs — the Sinaloa cartel, Los Zetas and La Familia Michoacana - have been placed on a list of significant foreign narcotics traffickers targeted for special sanctions, the White House said April 15.  This action allows the United States to freeze all cartel assets in U.S. jurisdiction and bars Americans from dealing with organizations that may be linked or associated with these groups and their operatives.
La Familia Michoacana are drug traffickers.
